Abstract

The invention belongs to the technical field of motors and discloses a variable-pole variable-phase dual-rotor axial magnetic flux annular winding synchronous motor comprising a stator and rotors, wherein the rotors comprise a right rotor, a left rotor and a rotor shaft; the right rotor and the left rotor are coaxially connected to the rotor shaft; the stator is disposed between the right rotor and the left rotor; independent air gaps are arranged between the right rotor and the stator and between the left rotor and the stator; the stator comprises a stator core and a stator annular winding; the stator core is a disc-shaped annular core; the stator annular winding is connected with an inverter; the left and right rotors each comprise a rotor core and an exciting winding; the stator annularwinding corresponds to the exciting winding; and the exciting winding is connected to a controllable DC power supply. The variable pole and the variable phase of the motor are achieved by changing the direction and the magnitude of the exciting current and the magnitude and the phase of the armature current. The phase number and the pole number of the motor can be changed in a non-stop manner, and the speed of the motor can be regulated within a wide range.

Description

technical field [0001] The invention belongs to the technical field of motors, and relates to a pole-changing phase-changing dual-rotor axial flux ring winding synchronous motor. Background technique [0002] AC motor speed regulation is an important topic in motor applications. Among all motor loads, about 50% are load changes, and 30% of them can meet the requirements of load changes through motor speed regulation. The requirements for motor speed regulation are common in all walks of life. [0003] In order to realize the speed regulation of the AC motor, at present, the speed regulation of the AC motor is mainly realized through frequency conversion or pole changing. The pole-changing speed regulation method obtains a variety of pole pairs by changing the winding connection, so that a motor can run with different pole pairs in different speed ranges. Existing pole-changing motors generally adopt a multi-winding structure. When one set of windings is working, the other ...
