Abstract

The invention discloses a side-control pole-changing motor system. The side-control pole-changing motor system is composed of an excitation coil 1, a side I-shaped magnetic conductor 2, a motor coil 3, a side motor magnetic conductor 4, an active magnetic control system lidesheng 14 and the like. The built-in control information of the active magnetic control system lidesheng 14 is respectively output through a first active magnetic control system lidesheng control port 9, a first input port 7 and a second active magnetic control system lidesheng control port 13 for supplying power to the excitation coil 1 through a second input port 10, the excitation coil 1 generates an N/S variable polar magnetic field after obtaining electricity, the motor coil 3 is cut by the N/S variable polar magnetic field generated by the excitation coil 1 and a rotor synchronously, the motor coil 3 generates a driving magnetic field through cutting magnetic lines of force, and a power supply input inputs electric energy through a first power supply input port 15 and a second power supply input port 16 respectively. Therefore, the side-control pole-changing motor system achieves the purpose of adjusting stability of the motor in a pole-changing manner by changing rotating speed in a cycle.

Description

technical field [0001] The invention relates to a side-controlled pole-changing motor technology for multi-field applications such as active magnetism, and in particular to a device that uses a side I-shaped magnetic conductor to control the forward and reverse of the wire-wrapped current and the size of the wire-wrapped current; Motors, electric vehicles, fans, air compressors and other electric devices driven by unequal speeds (referred to as "side-controlled pole-changing motor systems").
