    Ceiling fan works on AC mains 50 / 60 Hz, it does not seem a good idea to control speed by frequency control using microcontroller. If at all a microcontroller is to be brought in, stepping or switching using a triac can be considered.

    Even if I use a 3 phase motor it also runs on 50-60Hz frequency.

    Help me out here, I need to complete this project by December or I am goner.
