kiln drive of cement mills,
rolling mill drives and
Let me start with the type of motor used in a ceiling fan:
In the conventional ceiling fans used in our homes, a single phase induction motor is used. Many call these as fractional kilowatt motors because they use minimum amount of power. This is a schematic diagram of a single phase motor.
Generally we use a capacitor start & run an AC Motor for ceiling fans.
