Abstract

The invention provides a novel magnetic circuit structure motor. The motor comprises a stator assembly and a rotor assembly, wherein the stator assembly is provided with a winding and a magnetic conduction element, and the rotor assembly is fixed with an array of permanent magnets. The radial distance of the working surface of the stator assembly has a fluctuation variation period along the circumferential direction, and the radial distance of the working surface of the permanent magnet array has a fluctuation variation period along the circumferential direction. The width of the working surface of the permanent magnet of the permanent magnet array is at least 1.5 times the circumferential width of the working face of the crown of the stator assembly along the circumferential direction. When the permanent magnet and the teeth of the stator assembly move relative to each other, a finer air gap with a fluctuation period is generated between the working surface of the crown and the working surface of the permanent magnet, and the working efficiency of the motor is improved.

Description

technical field

[0001] The invention relates to the field of motors, in particular to a motor with a novel magnetic circuit structure. Background technique

[0002] A motor is a common driving device in daily life, which can convert electrical energy into mechanical energy. The motor includes a stator assembly and a rotor assembly, and the rotation of the rotor assembly relative to the stator assembly is realized by means of electromagnetic transformation, and the rotor assembly outputs power through a rotating shaft. However, the magnetic field strength between the permanent magnet and the teeth of the motor is relatively concentrated, which reduces the stability of the rotor assembly of the motor, increases the rotational load loss of the motor, and reduces the working efficiency of the motor.
