摘要

同轴磁齿轮是一种结构新颖的传动装置，在低速大转矩传动领域具有广阔应用前景。针对传统表贴式磁齿轮气隙磁密谐波含量高、转矩脉动大的问题，本文提出了一种内磁极为偏心表贴式，外磁极为永磁体励磁和电励磁两种磁化方式的同轴式磁齿轮。利用有限元法计算了传统型、开槽未加电流型和开槽加电流型磁齿轮的气隙磁场和电磁转矩，对内、外层气隙磁密的谐波含量进行了分析。仿真结果表明，偏心磁极结构有利于改善内层磁密波形，降低谐波畸变率；增加电流励磁不仅能保证输出转矩，而且能降低转矩脉动。这对提高同轴磁齿轮的传动稳定性具有重要意义。

Abstract

Coaxial magnetic gear is a novel transmission device with wide application prospects in low speed and large torque transmission field.Here, in order to solve the problem of traditional surface mounted magnetic gear having high harmonic content and large torque ripple in air-gap magnetic density,a coaxial magnetic gear with eccentric surface mounted inner magnetic pole and external magnetic pole magnetized by two modes of permanent magnet and electric excitation was proposed.The finite element method was used to calculate air-gap magnetic field and electromagnetic torque of traditional type, slotted without current type and slotted current type magnetic gears, and harmonic contents of inner layer air-gap magnetic density and outer onewereanalyzed.The simulation results showed that the eccentricmagnetic pole structure is beneficial to improve inner layer magnetic density waveform and reduce its harmonic distortion rate; increasing current excitation can not only guarantee output torque but also reduce torque ripple,this is of great significance for improving the transmission stability of coaxial magnetic gears.
