Description
The main intention of this project is to develop an induction motor speed control system which is helpful to control the speed of an induction motor using microcontroller
In this project, the zero-crossing point of the voltage waveform is detected by a comparator whose output is then fed to the microcontroller. Then, it provides the required delayed triggering pulses to a pair of TRIAC through an opto-isolator connected to this circuit. Finally, power is applied to the load through the TRIAC. Four push-button switches are interfaced to the controller for increasing and decreasing the AC power to the load. In this project, a lamp is used in the place of induction motor demonstration purposes. The motor speed variation depends on the power reduction.
HIGHLIGHTS
- Microcontroller is used
 - The zero-crossing detector
 - upto-coupler is used to isolate
 - Power is applied through the TRAIC

Ankush –
Excellent concept of “project kit” is very usefull to every one in their career. Every thing is available on the website…and also i was check all other projects from electrosal website that is away-some.thank you Electrosal for helping us in our final year project.
Mayur Lohar –
Best place for innovation …
Had a good experience,learnt very helpful things about electronics
