Abstract
A method for controlling outputs of electric motors includes the steps of (a) providing an electric motor including a stator winding unit selected from first to fourth winding groups, each of the winding groups having at least a primary winding with a first number of poles and a first rated power, and at least a secondary winding with a second number of poles being the same as or different from the first number of poles and a second rated power being the same as or different from the first rated power; and (b) providing a control device respectively coupled with the electric motor and an external electrical power source for sensing a needed loading state of the electric motor and suppling a required connection relationship between the stator winding unit and the external electrical power source based on the needed loading state sensed by the control device.
