7. TYPES OF MACHINE
DC Machine consists:-
1. Separately excited DC Motor/ Generator
2. DC Series Motor/ Generator
3. DC Shunt Motor / Generator
4. Compound motor / Generator
Induction Machine Consists:-
1. Single Phase Induction Motor/ Generator
2. Three Phase Induction Motor/ Generator
Synchronous Machine Consists:-
1. Rotating Armature Type
2. Rotating Field Type

8. PRINCIPLE OF OPERATION OF SYNCHRONOUS
GENERATOR
 The synchronous generator works on the principle of Faraday
laws of electromagnetic induction.
 In order to generate electricity in the three phase winding, we need variation of flux or variation in
number of turns.
 So we use the rotation of DC flux in air gap as a varying field.
 Rotation of DC flux appears as varying field to the 3 phase stationary winding.
 EMF will also be generated due the relative motion between
the conductor and the field induces the EMF in the conductor.
 EMF will be shifted by 120 degree due to displacement by 120 degree in space between windings.

9. STARTING OF INDUCTION MOTOR
Why starting current is high?
• Because at starting, slip=1, so impedance would be minimum so starting current would be high.
• We need to reduce starting current and increase starting torque.
Importance of Induction Machines:-
• Wound rotor motors are suitable for loads requiring high starting torque and where a lower starting current
is required.
• Induction motors are used for the loads that require speed control.
• Induction motors are used in cranes, pumps, elevators and compressors.
• Induction generator requires less maintenance because of its robust construction.
• Cage motor is used as an induction generator as it is cheaper in
comparison.
• Induction generator does not require synchronization as synchronous motor.
• Induction generator is used in wind farms to generate electricity.

12. WORKING PRINCIPLE
An electric motor is an electrical machine which converts electrical energy
into mechanical energy. The basic working principle of a DC motor is:
"whenever a current carrying conductor is placed in a magnetic field, it
experiences a mechanical force

13. WORKING PRINCIPLE OF AC MOTOR
An AC motor works by applying alternating current to stator windings, which
produce a rotating magnetic field. Because the magnetic field rotates in this way,
an AC motor does not need power or mechanical aid to be applied to the rotor

CASCADE OPERATION
Entities that use
relationships often have
dependencies on the
existence of the other
entity in the relationship
With the
same rheostat added to
the rotor circuit, it is
possible to regulate the
speed of slip ring motors

15. WORKING PRINCIPLE OF DC MOTOR
The DC motor is the device which converts the direct current into the
mechanical work. It works on the principle of Lorentz Law, which states that
“the current-carrying conductor placed in a magnetic and
electric field experience a force”. The experienced force is called the Lorentz
force

16. SPEED CONTROL OF DC
MOTOR
FLUX CONTROL
METHOD
• This can be achieved by using
a variable resistor in a series
with the field winding resistor.
• Initially, when the variable
resistor is kept at its minimum
position, the rated current flows
through the field winding due to
a rated supply voltage, and as
a result, the speed is kept
normaL
ARMATURE CONTROL
METHOD
• One way is by
implementing armature resistance, which
involves connecting a variable resistance in
series to the circuit of the armature.
• Once resistance has been increased, the
current flow through the circuit is reduced
and the armature voltage drop is less than
the line voltage.

17. PLC & AC DRIVE WITH AUTOMATIC
AND MANUAL INDUSTRIAL CONTROL

18. PLC FOR AUTOMATION CONTROL
* The programming device is used to insert the program in memory
of the processor. The personal computer is the device used to
elaborate the logics, usually in ladder, and can be transferred to
the PLC via link or ethernet. The program is a series of
commands developed according to the needs of the user.
* Learning different language for programing plc like
LADDER,FBD and STL.

19. LANGUAGES IN PLC
1.Ladder - Ladder logic is used to develop software for programmable
logic controllers (PLCs) used in industrial control applications. The
name is based on the observation that programs in this language
resemble ladders, with two vertical rails and a series of horizontal rungs
between them.
2.FBD -The Function Block Diagram (FBD) is a graphical language for
programmable logic controller design, that can describe the function
between input variables and output variables.
3.STL - The Statement List (STL) programming language is one of the
three programming languages available in the basic STEP 7 software
package. It is a text-based programming language with a structure
similar to assembly language or machine code. STL is the
native language of S7-300 and S7-400 processors.

20. TYPE OF SENSOR

21. DEFINATION :
1.ACTIVE SENSOR -A Thermocouple is an Active Sensor as it
does not require any external power supply to operate.
2. PASSIVE SENSOR -A Passive Sensor requires an external
source of power to operate while an Active Sensor does not.

22. SYSTEM DYNAMICS AND CONTROL

23. INTRODUCTION :
• System dynamics is a highly abstract method of modeling. It
ignores the fine details of a system, such as the individual
properties of people, products, or events, and produces a general
representation of a complex system. Abstract simulation models
may be used for long-term, strategic modeling and simulation..
• The Dynamics and Control Group addresses research problems
relating to modelling, simulation and control of civil, mechanical
and aerospace engineering systems.

28. Matrix and Operators:-
• Higher dimensions are uncommon
• The most common have special names:
• 2D array = “matrix” (plural is “matrices”)
• 1D array = “vector”
• Most ingenious part of Cleve Moler’s invention of MATLAB was the way he set
it up to deal with matrices.
• MATLAB stands for “Matrix Laboratory”!
• Matrix Multiplication:-
• Different from Array Multiplication!
• Z = X * Y means that for all valid m and n
• Inner dimensions of X and Y must be the same.
