Abstract

The application of coaxial magnetic gear (CMG) in wave generator instead of traditional variable speed gearbox can effectively improve torque density and reduce torque ripple. Thus, the operation principle of CMG from the perspective of magnetic field modulation is firstly analyzed in this paper. Then the air gap magnetic fields induced by high-speed and low-speed rotors are studied. And the radial height, inner diameter angle, and outer diameter angle of the modulating pieces (MPs) are optimized by using the combination of response surface method (RSM) and particle swarm optimization (PSO) algorithm to improve the torque transmission capacity of CMG. The CMG is combined with the permanent magnet synchronous machine to get the magnetic-gear permanent magnet synchronous generator (MG-PMSG). The design feasibility of the MG-PMSG is verified from four aspects: static magnetic field analysis, no-load characteristics, load characteristics and load disturbance analysis.

同轴磁齿轮的优化及其在波浪发电中的应用

将同轴磁齿轮(CMG)应用于波浪发电机中，可以有效地提高转矩密度，减小转矩脉动。因此，本文首先从磁场调制的角度分析了CMG的工作原理。然后对高速和低速转子产生的气隙磁场进行了研究。采用响应面法(RSM)和粒子群算法(PSO)相结合的方法对调制件的径向高度、内径角和外径角进行优化，提高了调制件的转矩传递能力。将永磁同步电机与永磁同步电机组合为永磁齿轮同步发电机(MG-PMSG)。从静磁场分析、空载特性分析、负载特性分析和负载扰动分析四个方面验证了MG-PMSG设计的可行性。
