In an intelligent electric motor, the rotating speed and performance of a conventional electric motor is changed based on a means controlled by a computer, and the means is installed in the housing of the intelligent electric motor. For example, in the intelligent AC motor, the three-phase power is connected to the three-phase stator winding by three groups of control gates. All of the gates are switched on or off by a signal from the control means. When each of the three groups of control gates is switched on sequentially, the three-phase power is connected to the three-phase stator winding of the three-phase intelligent electric motor at the speed delta in turn, so that the speed of the rotating magnetic field of the intelligent electric motor n0 is increased by a sped delta. Therefore, the actual speed of the motor, n'0, is equal to n0±delta, so the speed and performance of the motor is changed.
