I'd reckon that the standard frequency is 50 or 60 Hz depending on the particular country. For India it is 50 Hz.

However an AC motor's speed can also be varied by varying the frequency instead of the voltage, since the speed is directly proportional to both the voltage and frequency (within limits, of course).

The following image will help which is from PIC 16f877A data sheet, You can vary the speed by adjusting duty cycle .
