Analysis of the Drive Characteristic of Composite Magnetic Gear Motor

为探讨磁场调制式磁力齿轮在电动车驱动中的应用,首先结合磁场调制式磁力齿轮的基本原理,将电机嵌套在磁场调制式磁力齿轮的内转子内,组成复合电机;其次应用电机学和电磁学理论,对其进行建模,并将其应用于电动自行车上,建立其受力模型,研究电动自行车在水平路面行驶和爬坡时的启动、巡航的运动状态。仿真结果表明,装配有磁场调制式磁力齿轮的电动自行车,无论在水平路面还是斜坡上,都可以达到期望的速度并保持平稳行驶,取得了理想的效果。

Aiming at investigating the applications of field modulated magnetic gear（FMMG）in e- lectric vehicle drive, firstly, combined with the basic principle of magnetic gear, a new motor combined with the FMMG when it is embedded into the ordinary permanent magnet motor is gained, its simula- tion model is established by applying the principles of electromagnetic and electric machinery. Then the combined motor is applied to electric bicycle and its force model is built to research electric bicycle start state and cruise state on a level surface and slope pavement respectively. Simulation results show that the electric bicycle equipped with FMMG,whether on a level surface or on the slopes, can achieve the desired speed and keep a smooth ride, the desired result is got.
