Abstract

The present invention provides a magnetic gear and a composite motor with it, wherein the magnetic gear includes: an inner rotor body, on which a plurality of inner rotor permanent magnets are arranged, and the plurality of inner rotor permanent magnets are arranged along the circumference of the inner rotor body The direction is arranged at intervals; the outer rotor body is provided with a plurality of outer rotor permanent magnets, and the plurality of outer rotor permanent magnets are arranged at intervals along the circumferential direction of the outer rotor body; the modulation ring, the modulation ring includes a plurality of modulation blocks and magnetic bridges , two adjacent modulation blocks are connected by a magnetic bridge; the radial section of the modulation block and the radial section of the magnetic bridge are both fan-shaped, and the center of the fan ring is the center of the modulation ring; the radial section of the modulation block is The corresponding central angle is θ1, and the corresponding central angle of the magnetic bridge is θ2, 0.3<θ1 / θ2<0.96. The present invention solves the problem of large torque fluctuation of the magnetic gear in the prior art, which leads to poor performance of the magnetic gear.

Description

technical field [0001] The invention relates to the field of magnetic gears, in particular to a magnetic gear and a composite motor with the same. Background technique [0002] With the development of science and technology, people's requirements for the performance of the transmission system are gradually increasing. The traditional mechanical gears have been unable to meet the application requirements due to their shortcomings such as high noise and low transmission efficiency. Therefore, magnetic gears have gradually developed. Due to its simple structure , low vibration and noise, overload self-protection and high operational reliability have become research hotspots. [0003] The magnetic gear mainly includes three parts: the inner rotor, the outer rotor and the modulation ring. Most of the modulation rings in the prior art are composed of two end rings and a plurality of magnetic blocks. The end rings and the magnetic blocks are locked by screws. The two adjacent magn...
