Why the Direction of Rotation of a TABLE Fan & CEILING Fan is different?

ceiling-fan runs anticlockwise and  the table-fan runs clockwise.In table fan rotor is rotating part, but in ceiling fan stator is rotating part, so the direction of rotation is different.stator has magnetic poles which generate magnetic flux. This interacts with the Continue reading
