Externally controlled pole-changing motor system

Abstract

The invention creatively discloses an externally controlled pole-changing motor system, which comprises an excitation solenoid (1), an outer ring magnetizer (2), a motor solenoid (3), an inner motor magnetizer (4), an active magnetic control system lidesheng (14) and the like in common, wherein built-in control information of the active magnetic control system lidesheng (14) is output through a control port 1 of an active magnetic control system lidesheng (9), is output through an input port 1 (7) and a control port 2 of an active magnetic control system lidesheng (13), and supplies electricity to the excitation solenoid (1) through an input port 2 (10); the excitation solenoid (1) is electrified to generate a polar magnetic field with a variable N / S; the variable polar magnetic field generated by the excitation solenoid (1) and a rotor synchronously cut the motor solenoid (3); the motor solenoid (3) generates a drive magnetic field by a cutting magnetic line; and a power supply input inputs electric energy through a power supply input port 1 (15) and a power supply input port 2 (16) respectively, so that the targets of changing of a rotating speed within a cycle and adjusting of the stability of a motor in a pole-changing manner are achieved.

Description

technical field [0001] The invention relates to an externally controlled pole-changing motor technology for multi-field applications such as active magnetism, and in particular to a device that uses an outer annular magnetizer to control the forward and reverse direction of the wire-wrapped current and the size of the wire-wrapped current; Electric vehicles, electric vehicles, fans, air compressors and other electric devices driven by unequal speeds (referred to as "external control pole-changing motor system").
