about ac motor controlling

[thomas33]

hai all,we are doing a project of ac motor controlling.could you please tell which is the most efficient method for doing that and shall you please tell which microcontroller is suitable.

we are doing a project on ac motor controlling.For that we should vary the supply frequency.we heard about IGBT.Actually how IGBT vary the width of the supply and do you have any suggestion for doing that and which microcontroller is more suitable for doing that.

how IGBT vary the width of the supply

I think you are talking about frequency converter and PWM voltage/current controller.
