Introdution The speed of the AC motor is controlled by the SCR It is

based on micro controller its suitable for control the ACmachine .

All circuits are mounted on the motor which is controlledby RF transmittor through the PC .

The programming in C .it controlling the motor speedand auto cut off when the temperature is high and during

the over load.

Aim of the design is to develop a

system based on Embedded microcontroller (8051), which is used as

remote controlled speed regulation

of induction motor with SCR andZVS.

Project ObjectivesTechnology today is seeing its heights in all

the areas, especially in the area of

Embedded Systems. It is true that every electronic gadget that is

used in daily life right from a PC keyboard to

a refrigerator is an Embedded System.

SWITCHING UNIT:

There is two type of controls e.g.

Direction control (clock wise,Anti clock wise)

Speed control (Increasing,decreasing)


11/17

TECHNOLOGY USEDHere we are controlling the speed of AC

induction motor by applying the PWM

(pulse width modulation) which willdependent on the ZVS technique.

In this system, embedded controller is used

to generate the PWM pulses throughThyristor, which controls the speed controlof AC motor.

SoftwareA Cross compiler for compiling and linking the code

written for AT898C51.

Serial communication software for downloading codeto AT89C51.

Embedded C for application program development.

Operating System: Windows 2000/XP/7.


13/17

Hardware Serial communication used for downloading the hex

code.

Thyristor interface to micro controller. Interfacing with AC motor through Buffer.

TV remote interface.

ZVS implementation

APPLICATIONFan/Exhaust

Washing Machine

Grinder MixtureLift Door Control

Lift Elevation

Milling System

Auto Transportation Using Conveyor Belt Etc..

ADVANTAGES It can control the motor on and off through the PC

RF transmitter and receiver is used for

communication in between dc motor and the operator It can sense the temperature of the motor and

switched off automatically

It sense the over load and cut the load automatically

Future enhancementThrough internet access

PLC ,SCADASpeed control using bluetooth
