I want to control speed by Microcontroller for Ac motor (induction motor).
i dont know any thing about IGBT but i know that should used it for speed control circuit.

please give me doc for research.
please help me

The AC induction motor may be three phase, capacitor start or a shaded pole type.

If you need a precise speed, you need to have a motor with built in feedback. Some of them can be used as position sensor.

The current fashion is a vfd- variable frequency drive- it works like a charm on three phase drives. They tend to be more complex.

Give more details on what you want, time you want to spend and your familiarity with the topic.
