UNIVERSAL DRIVER USING µc P89c51
INTRODUCTION:
* Motors are considered as one of the most importantpart of an Industry.
All the functions of the industries works on different types of motors.
There are various types of motors being used in industry depending
upon its application. The Ac and Dc motor required different type of
controller to control the speed of motor .
* But actually our aim to design universaldrive controller.
* The Whole hardwarestructurecan be processed in a single central unit
and can be termed as a universalcontroller. Temperature sensors,
Currentsensors, Speed sensors etc can be included into the hardwareas
per the application requirement .

3. Methodology:
There are two methods used while designing the controller
DC Controller:
For DC motor control is done by using a simple voltage divider method.
AC Controller:
Why use PWMfor speed variation?
When an AC motor is connected directly to an AC line (415V 3Φfor
example) the motor speed is fixed and is calculated as follows
𝑛𝑠=120∗𝑓/𝑝 − 𝑠𝑙𝑖𝑝
ns = Motor speed (RPM)
f = fundamental frequency(Hz)
p = no. of poles

4. 8051 micro-controller(P89V51RD2):
Features:-
8051 Central Processing Unit
5 V Operating voltage from 0 to 40 MHz
64kBof on-chip Flash program memory
Supports12-clock/6-clockmode
SPI(SerialPeripheralInterface)
Three 16-bit timers/counters
TTL- and CMOS-compatiblelogic levels
RXD/TXD Pins available
5. L293D (Motor Driver IC):
Wide Supply-VoltageRange: 4.5 V to 36 V.
Separate Input-Logic Supply.
Thermal Shutdown.
High-Noise-Immunity Inputs.
Peak OutputCurrent 2 A Per Channel (1.2 A for L293D)
6. Software Required:
FLASH MAGIC - This softwarehelps to dump the program opcodes to the
microcontroller. This allows easy access to all the ISP features by the
device. i.e. programming the flash memory, Reading from flash memory.
Embedded PCB Designer - This will help for designing the circuit on the
printed circuit board.
MATLAB version2012–This softwarewould providea graphicaluser
interface (GUI) between machine and man it will be used for creating a
graphical user interface for the application with the help of components
available on the window. The application softwareto interface hardware
systemconnected to PC using COM ports and provideGUI interface.
Advantages
A controller design for Torquecontrol of AC & DC motor
Starter-less operation.
The Whole hardwarestructurecan be Reconfigurable as universal
controller.
This controller also gives an intelligent motor control (IMC) operation.
Speed control of any motor is important because required speed to
accomplish a specific task
Application
This systemmay be used to run High graded IndustrialMotors according
to speed requirement.
Both AC as well as DC Drive will be in on system.
The systemwill be softwarecontrolled. So the user can enable or disable
the systemfromhis/her office room.
