An axial magnetic field motor with adjustable air gap

Abstract

The present invention provides an axial field motor with an adjustable air gap, comprising: a housing; a stator assembly configured as an annular structure fixedly arranged in the housing; a main shaft passing through the housing, and It is rotatably connected with the housing through a bearing; the connector is configured as a circular structure, and is fitted on the main shaft, and torque can be transmitted between the connector and the main shaft, and the connector can be moved along the The axial sliding of the main shaft; the rotor assembly is configured as a circular structure, which is fixedly connected with the connector, so that the rotor assembly can rotate synchronously with the connector; the adjustment structure is rotatably connected with the connector , for adjusting the position of the connector in the axial direction of the main shaft, so as to adjust the size of the air gap between the rotor assembly and the stator assembly. The invention can increase the gap between the rotor assembly and the stator assembly to reduce the magnetic density of the air gap, so that the motor can operate at a higher speed.

Description

technical field [0001] The invention relates to the technical field related to motors, in particular to an axial magnetic field motor with an adjustable air gap. Background technique [0002] The axial field permanent magnet motor is a new type of motor with short axial dimension, high power density and easy assembly. It has been used in electric vehicles, mobile generator sets, ship propulsion systems and other fields. Commonly used axial field motors have various forms of structures, among which the axial motor with single rotor and single stator structure is relatively easy to manufacture and assemble, and the price is low, so it is more popular. The stator structure with iron core is adopted, the stator form is basically fixed, and the air gap between the rotor and the stator is fixed. Under the existing axial motor control technology, it is difficult for the motor to weaken the magnetic field at high speed. The air gap surface of the axial motor magnetic steel is often...
