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 δ in turn, so that the speed of the rotating magnetic field of the intelligent electric motor n0 is increased by a sped δ. Therefore, the actual speed of the motor, n′0, is equal to n0±δ, so the speed and performance of the motor is changed.
An intelligent electric motor and control system capable of operating either as an intelligent AC electric motor system or an intelligent DC electric motor system, comprising:
