Welcome to the forums.

Your post did not relate in any way to the thread it appeared in, so it has its own now.

The speed of an induction motor must be controlled by changing the frequency of the AC voltage applied to it. A TRIAC can be used to vary the speed of a universal brush motor, although PWM is much better.

Look for information about Variable Frequency Drive to see how to control your motor.
