5. Abstract
The project proposes an efficient implementation for IoT (Internet of Things) used for
monitoring and controlling the Industrial Machines via World Wide Web. Industries system uses
verity of devices as a user interface. They can communicate with automation network through an
Internet gateway, by means of low power communication protocols like Zigbee, Wi-Fi etc. This
project aims at controlling industrial machines via Smartphone using Wi-Fi as communication
protocol and arduino as server system. The user here will move directly with the system through
a web-based interface over the web, whereas machines are remotely controlled through easy
website. In this study, a factory induction motor (IM) was monitored with wireless TCP/IP
protocol in order to detect and predict deviations from normal operating parameters before the
occurrence of motor failure. In this way, the production process is not impeded and the required
maintenance or replacement can be performed with the least possible disruption. In this study,
the motor cycle, the current drawn by the motor and the motor voltage were read by the Hall-
effect current sensor and the required power consumption was calculated. With this aim, the
designed architecture read the accepted parameters of the Motor and reported them to the central
management software. The central management software operating in real time was then able to
assemble these parameters and form predictive maintenance models.

CHAPTER 1
INTRODUCTION:
A universal motor is a special type of motor which is designed to run either on DC or single
phase AC supply. Universal Motors are so named because they can run both on AC as well as
DC. A universal motor has a high starting torque and variable speed characteristics. Such motor
runs at dangerously high speeds during no load [3].
Fig.1.1 Universal motor structure
The universal motor is basically a series DC motor which is specially designed to operate on AC
as well as on DC. A standard DC series motor has very poor characteristics when operated on
AC, mainly due to two reasons:
 The high reactance of both the armature and field windings limits AC current to a much
lower value than DC current for the same line voltage.
 If solid steel is used for the stator frame, AC flux will produce large eddy currents in the
frame with consequent heating.
To insure satisfactory operation of the universal motor from an AC power source, some
modifications are necessary. The reactance of the series field and armature windings must be
reduced as much as practicable. The reactance of the series field winding can be somewhat

9. Page- 2
reduced by using fewer turns of heavier wire. However, it would not be practical to eliminate the
reactance voltage drop due to the series field since that would also eliminate the magnetic field.
The reactance voltage drop due to the armature winding can be practically eliminated by use of a
compensating winding. The compensating winding is connected in series with the armature
winding (conductive compensation) and arranged such that the ampere-turns of the
compensating winding oppose and neutralize the ampere-turns of the armature. To realize this
compensation, the compensating winding is displaced by 90 electrical degrees from the field
winding.
The reactance of the armature winding can be lowered by placing a compensating winding on the
stator so that the fluxes oppose or “cancel” each other. This same compensating winding can be
connected in series with the armature winding. In this case, the motor is said to be conductively
compensated. Under these conditions, the universal motor will have similar operating
characteristics whether on AC or DC power.
The compensating winding may be simply shorted upon itself, so that it behaves like a short
circuited secondary of a transformer (the armature winding acting as the primary). The induced
AC current in the compensating winding again opposes the armature current and the motor is
said to be inductively compensated. The reactance of the field winding can be kept low by
limiting the number of turns [1].

Recent advances in processing technology the availability of fast-processing, stable and sensitive
products provided particular benefits in industrial automation. As a result of the recent
developments in Communication technologies, systems are no longer monitored and controlled
by manually using classic methods, but automatically by computer controlled or remote-
controlled devices. The future generation industries will be Technological developments have
enabled to be taken classic systems place by Automatic and advanced systems definitely more
advanced and automatic as compared with existing ones. This brings on a new terminology of
“Smart Industries” in this new era of Monitoring as well as controlling of various Industrial
applications. As an emerging technology in modern wireless telecommunication, Internet of
Things (IoT) has got a lot of attention and is expected to bring benefits to many applications. The
concept of “Internet of Things” (IOT) is providing a best way for Industrial automation through
remote access. In IOT each device or devices constituting a system will be able to communicate
with the other devices. Hence this leads to exchange of relevant data, statistics, logs and various
other parameters information among various devices to improve their performance, which will
help industries to have better productivity, management and increased throughput. Here in the
proposed work the IoT is used for monitoring and controlling the AC induction motor to avoid
the system failures [1].

2.2 SYSTEM DESIGN:
The Figure below shows overall model of proposed project, and following steps present its flow
of working.
 Once we switch on the system, Regulated power supply unit supplies required electrical
energy for all the equipment in proposed system.
 Sensor unit senses the corresponding motor parameters and feed to the arduio. Then
sends the sensor information to LCD and network gateway through Wi-Fi. In Parallel
arduino reads the commands from internet and provides control signals to the motor drive
(TRIAC), which will control the induction motor.
 The display unit provides the visual representation of sensor information.

12. Page- 5

HARDWARE AND SOFTWARE CONFIGURATION:
A. Hardware Components
For induction motor parameter monitoring we are using light weighted and easily configurable
sensors like piezoelectric sensor (accelerometer) for vibration, DH11 sensor for temperature and
humidity, infrared sensor for speed, ACS712 for current measurement and voltage divider for
voltage measurement. Microcontroller usage is best for acquiring data. arduino board has been
used for this research which has the ability to acquire sensor data, communicate with other
devices, store information in local, cloud server and alert the user when fault is detected. Fig. 3
shows block diagram of the hardware connections [2].
Component description:
1. Arduino is open-source hardware and software company, project and user community
that designs and manufactures single-board microcontrollers and microcontroller kits for
building digital devices and interactive objects that can sense and control objects in the
physical and digital world. Its products are licensed under the GNU Lesser General
Public License (LGPL) or the GNU General Public License (GPL),[1] permitting the
manufacture of Arduino boards and software distribution by anyone. Arduino boards are
available commercially in preassembled form or as do-it-yourself (DIY) kits. Arduino
board designs use a variety of microprocessors and controllers.
Fig.3.1 Image of AURDINO [2]
The boards are equipped with sets of digital and analog input/output (I/O) pins that may
be interfaced to various expansion boards or breadboards (shields) and other circuits. The
boards feature serial communications interfaces, including Universal Serial Bus (USB)
on some models, which are also used for loading programs from personal computers. The
microcontrollers are typically programmed using a dialect of features from the

14. Page- 7
programming languages C and C++. In addition to using traditional compiler tool chains,
the Arduino project provides an integrated development environment (IDE) based on
the Processing language project.
2. Node MCU is an open source IoT platform. It includes firmware which runs on
the ESP8266 Wi-Fi SoC from Espress if Systems, and hardware which is based on the
ESP-12 module. The term "Node MCU" by default refers to the firmware rather than the
development kits. The firmware uses the Lua scripting language. It is based on the eLua
project, and built on the Espress if Non-OS SDK for ESP8266. It uses many open source
projects, such as lua-cjson, and spiffs.
Fig.3.2 Image of Node MCU
3. TRIAC, from triode for alternating current, is a generic trademark for a three
terminal electronic component that conducts current in either direction when triggered. Its
formal name is bidirectional triode thyristor or bilateral triode thyristor. A thyristor is
analogous to a relay in that a small voltage and current can control a much larger voltage
and current. The illustration on the right shows the circuit symbol for a TRIAC where A1
is Anode 1, A2 is Anode 2, and G is Gate. Anode 1 and Anode 2 are normally termed
Main Terminal 1 (MT1) and Main Terminal 2 (MT2) respectively.
TRIACs are a subset of thyristors and are related to silicon controlled rectifiers (SCRs).
TRIACs differ from SCRs in that they allow current flow in both directions, whereas an
SCR can only conduct current in a single direction. Most TRIACs can be triggered by
applying either a positive or negative voltage to the gate (an SCR requires a positive
voltage). Once triggered, SCRs and TRIACs continue to conduct, even if the gate current
ceases, until the main current drops below a certain level called the holding current.
Gate turn-off thyristors (GTOs) are similar to TRIACs but provide more control by
turning off when the gate signal ceases. TRIACs bi-directionality makes them convenient
switches for alternating-current (AC). In addition, applying a trigger at a controlled phase

15. Page- 8
angle of the AC in the main circuit allows control of the average current flowing into a
load (phase control). This is commonly used for controlling the speed of induction
motors, dimming lamps, and controlling electric heaters.
Operation:

16. Page- 9
 Figure 3.3: Triggering modes. Quadrants, 1 (top right), 2 (top left), 3 (bottom left), 4 (bottom right)
Figure 3.4: TRIAC semiconductor construction
Understand how TRIACs work, consider the triggering in each of the four quadrants. The
four quadrants are illustrated in Figure 1, and depend on the gate and MT2 voltages with
respect to MT1. Main Terminal 1 (MT1) and Main Terminal (MT2) are also referred to
as Anode 1 (A1) and Anode 2 (A2) respectively. The relative sensitivity depends on the
physical structure of a particular triac, but as a rule, quadrant I is the most sensitive (least
gate current required), and quadrant 4 is the least sensitive (most gate current required).
In quadrants 1 and 2, MT2 is positive, and current flows from MT2 to MT1 through P, N,
P and N layers. The N region attached to MT2 does not participate significantly. In
quadrants 3 and 4, MT2 is negative, and current flows from MT1 to MT2, also through P,
N, P and N layers. The N region attached to MT2 is active, but the N region attached to
MT1 only participates in the initial triggering, not the bulk current flow.
In most applications, the gate current comes from MT2, so quadrants 1 and 3 are the only
operating modes (both gate and MT2 positive or negative against MT1). Other
applications with single polarity triggering from an IC or digital drive circuit operate in
quadrants 2 and 3, than MT1 is usually connected to positive voltage (e.g. +5V) and gate
is pulled down to 0V (ground).
4. Power supply: is an electrical device that supplies electric power to an electrical load.
The primary function of a power supply is to convert electric current from a source to the
correct voltage, current, and frequency to power the load. As a result, power supplies are
sometimes referred to as electric power converters. Some power supplies are separate

17. Page- 10
standalone pieces of equipment, while others are built into the load appliances that they
power. Examples of the latter include power supplies found in desktop
computers and consumer electronics devices. Other functions that power supplies may
perform include limiting the current drawn by the load to safe levels, shutting off the
current in the event of an electrical fault, power conditioning to prevent electronic
noise or voltage surges on the input from reaching the load, power-factor correction, and
storing energy so it can continue to power the load in the event of a temporary
interruption in the source power (uninterruptible power supply).
All power supplies have a power input connection, which receives energy in the form of
electric current from a source, and one or more power output connections that deliver
current to the load. The source power may come from the electric power grid, such as
an electrical outlet, energy storage devices such as batteries or fuel
cells, generators or alternators, solar power converters, or another power supply. The
input and output are usually hardwired circuit connections, though some power supplies
employ wireless energy transfer to power their loads without wired connections. Some
power supplies have other types of inputs and outputs as well, for functions such as
external monitoring and control.
AC-to-DC supply:
Schematic of basic AC-to-DC power supply, showing (from L-R) transformer, full-wave
bridge rectifier, filter capacitor and resistor load. DC power supplies use AC mains
electricity as an energy source. Such power supplies will employ a transformer to convert
the input voltage to a higher or lower AC voltage. A rectifier is used to convert the
transformer output voltage to a varying DC voltage, which in turn is passed through
an electronic filter to convert it to an unregulated DC voltage.
Fig.3.5 Full wave bridge rectifier

18. Page- 11
The filter removes most, but not all of the AC voltage variations; the remaining AC
voltage is known as ripple. The electric load's tolerance of ripple dictates the minimum
amount of filtering that must be provided by a power supply. In some applications, high
ripple is tolerated and therefore no filtering is required. For example, in some battery
charging applications it is possible to implement a mains-powered DC power supply with
nothing more than a transformer and a single rectifier diode, with a resistor in series with
the output to limit charging current.
5. LM35 Temperature sensor: The LM35 series are precision integrated-circuit
temperature devices with an output voltage linearly-proportional to the Centigrade
temperature. The LM35 device has an advantage over linear temperature sensors
calibrated in Kelvin, as the user is not required to subtract a large constant voltage from
the output to obtain convenient Centigrade scaling. The LM35 device does not require
any external calibration or trimming to provide typical accuracies of ±¼°C at room
temperature and ±¾°C over a full −55°C to 150°C temperature range. Lower cost is
assured by trimming and calibration at the wafer level. The low-output impedance, linear
output, and precise inherent calibration of the LM35 device makes interfacing to readout
or control circuitry especially easy. The device is used with single power supplies, or
with plus and minus supplies. As the LM35 device draws only 60 µA from the supply, it
has very low self-heating of less than 0.1°C in still air. The LM35 device is rated to
operate over a −55°C to 150°C temperature range, while the LM35C device is rated for a
−40°C to 110°C range (−10° with improved accuracy). The LM35-series devices are
available packaged in hermetic TO transistor packages, while the LM35C, LM35CA, and
LM35D devices are available in the plastic TO-92 transistor package. The LM35D device
is available in an 8-lead surface-mount small-outline package and a plastic TO-220
package.

6. Speed sensor: The Hall Effect is the production of a voltage difference (the Hall voltage)
across an electrical conductor, transverse to an electric current in the conductor and to an
applied magnetic field perpendicular to the current. It was discovered by Edwin Hall in
1879.For clarity, the original effect is sometimes called the ordinary Hall Effect to
distinguish it from other "Hall effects" which have different physical mechanisms. The
Hall coefficient is defined as the ratio of the induced electric field to the product of the
current density and the applied magnetic field. It is a characteristic of the material from
which the conductor is made, since its value depends on the type, number, and properties
of the charge carriers that constitute the current.

interfaces on upper and bottom sides of the LCD module. This 16x2 lcd display has the
outline size of 80.0 x 36.0 mm and VA size of 66.0 x 16.0 mm and the maximum
thickness is 13.2 mm. WH1602W 16x2 LCD Displays are built-in controller ST7066 or
equivalent. It is optional for + 5.0 V or + 3.0 V power supply. The LEDs can be driven by

CHAPTER 4
Cloud Storage & SOFTWARE:
Data that is obtained from the sensors are transferred wirelessly to the local and cloud server for
analysis. Once the data is received, a system has been devised that analyzes the raw data. The
program has been set to process real-time data and store it to the cloud with Thing speak cloud
computing platform. This saved data is accessible from anywhere via internet. Here we are going
to use firebase as the data store cloud resource please a quick look over the firebase:
FIREBASE: Firebase is a mobile and web app development platform that provides developers
with a plethora of tools and services to help them develop high-quality apps, grow their user
base, and earn more profit. [2]

CHAPTER 5
MOTOR CONTROL
Universal DC Motor Control Algorithms
Speed control of Universal Motors typically employs two schemes:
1. Phase angle Control
2. PWM Chopper control
Phase Angle Control: It is the simplest method to control the speed of a universal motor.
Speed control is achieved by the varying the firing angle for the TRIAC. Phase angle control is
very cost effective solution but not very efficient and prone to EMI.
Fig.5.1 Phase Angle Control of a Universal Motor
Figure above shows the Phase Angle Control mechanism typically employed for speed control of
the TRIAC. A phase shift of the TRIAC gate's pulses allows the effective voltage, seen by the
motor to be varied and hence the speed of the motor. A Zero Crossing Detection circuit is used to
establish a timing reference for delaying the firing of the gate pulses.

24. Page- 17
PWM Chopper Control: PWM control is a more advanced solution for controlling the speed of
a universal motor. In this method rectified AC line voltage is switched at a high frequency by a
Power MOFSET or IGBT device to generate time varying voltage for the motor.
Fig.5.2 PWM Chopper Control of a Universal Motor
The switching frequency is usually in the range of 10 to 20 KHz so as to eliminate acoustic
noise. This method of universal motor control can achieve better current control, better EMI
behavior and hence more efficient.

CHAPTER 6
PCB DEIGN PROCESS:
A printed circuit board (PCB )mechanically supports and electrically connects electronic
components using conductive tracks, pads and other features etched from copper sheets laminated
onto a non-conductive substrate .Components –capacitors, resistors or active devices –are
generally soldered on the PCB .Advanced PCBs may contain components embedded in the
substrate.PCBs can be single sided (one copper layer, )double sided ( two copper layers )or Multi-
layer( outer and inner layers .)Conductors on different layers are connected with via Multi-layer
PCBs allow for much higher component density .Printed circuit boards are used in all but the
simplest electronic products .Alternatives to PCBs include wire wrap and point-to-point
construction .PCBs require the additional design effort to lay out the circuit, but manufacturing
and assembly can be automated .Manufacturing circuits with PCBs is cheaper and faster than with
other wiring methods as components are mounted and wired with one single part.A minimal PCB
with a single component used for easier modeling is called breakout board .[2]
For PCB fabrication, some basic steps have to be followed:
 PCB Etching process
 PCB Drilling
 Conductor plating
 Solder resist
 PCB Testing
 PCB Assembling
PCB Etching Process: All PCB’s are made by bounding a layer of copper over the entire
substrate, sometimes on both sides .Etching process has to be done to remove unnecessary
copper after applying a temporary mask, leaving only the desired copper traces.
Though there are many methods available for etching, the most common method used by
electronics hobbyists is etching using fecl3 or ferric chloride both are abundant and cheap.

26. Page- 19
Fig.6.1: PCB Etching
PCB Drilling: The components that have to be attached to the PCB can be done only by VIAS
drilling .That is, a pated-through hole is drilled in the shape of angular rings .Small drill bits that
are made out of tungsten carbide is used for the drilling .A dreamed drill press is normally used
to punch the holes .Usually, a drill of 0.035 inch.
Fig.6.2 PCB Drilling
Conductor plating- The outer layer of the PCB contains copper connection( part where the
components are placed )which does not allow solder ability of the components .To make it solder
able, the surface of the material has to be plated with gold, tin, nickel.

27. Page- 20
Fig.6.3 Conductor Plating
Solder Resist - The outer areas which are not to be solder able are to be covered with a solder
resist material .It is basically polymer coating that prevents the solder from bringing traces and
possibly creating shortcuts to nearby component leads.
PCB Testing - In industrial applications, PCB’s are tested by different methods such as bed of
nails test, rigid needle adaptor, CT scanning test and so on .The basic of all tests include a
computer program which will instruct the electrical test unit to apply a small voltage to each
contact point, and verify that a certain voltage appears at the appropriate contact points.
Fig.6.4 PCB Testing
PCB Assembling -
PCB assembling includes the assembling of electronics components on the respective holes in
the PCB .This can be done by through whole construction or surface mount construction .In the
former method, the component leads are inserted into the holes drilled in the PCB .In the latter
method, a pad having the legs similar to the PCB designing is inserted and IC’s are placed or
fixed on top of them .The common aspects in both the methods are that the components leads are
electrically and mechanically fixed to the board with a molten metal solder.

CHAPTER 7
CONCLUSION
This paper presents the concept of Internet of Things for early detection and monitoring of motor
system failures remotely. The system has been designed to combine various parameter
measurements in real-time, improving the delectability of different faults. The monitoring of the
motor system presents the measurement of different parameters namely temperature, speed,
moisture and consumption.
Thus, compared to conventional methods that relies solely on vibrations or temperature, this
design has more information sources which can enable an alarm. The concept of IoT is presented
here for remote monitoring and controlling the motor. The data received by the coordinator node
is stored and graphically presented in real-time by means of a application developed in visual
basics. The proposed system can be easily upgraded to add other sensors on the sensing node for
the measurement of other parameters if required. The system has a high autonomy, easy
installation and low maintenance costs. Experimental results confirm the feasibility of the
implementation of the system.
