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)

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.

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
