Abstract

The invention provides an axial magnetic field motor with an adjustable air gap. The axial magnetic field motor comprises a shell; a stator assembly constructed to be of an annular structure and fixedly arranged in the shell; a main shaft arranged on the shell in a penetrating manner and rotatably connected with the shell through a bearing; a connector, in an annular structure and arranged on themain shaft in a sleeving mode, torque can be transmitted between the connector and the main shaft, and the connector can slide in the axial direction of the main shaft; a rotor assembly in an annularstructure and fixedly connected with the connector, so that the rotor assembly can synchronously rotate with the connector; and an adjusting structure, rotatably connected with the connector and usedfor adjusting the position of the connector in the axial direction of the main shaft so as to adjust the size of an air gap between the rotor assembly and the stator assembly. By enlarging the gap between the rotor assembly and the stator assembly, the air gap flux density can be reduced, so that the motor can operate under the working condition of higher rotating 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...
