Study on Performance Factor of Affecting Directly-Driven Magnetic Field Modulation Permanent-Magnet Motor

分析现有直驱永磁电机结构形式;基于不同永磁体排布对直驱磁场调制永磁电机拓扑进行结构衍生;对比分析永磁体排布对直驱磁场调制永磁电机磁场影响;以Halbach型磁场调制永磁电机为对象,结合正交试验法探究影响该类电机性能的关键参数。

This paper analyzes the structural type of the existing directly-driven permanent magnet motor,derives the topology structure of the directly-driven magnetic-field modulation permanent magnet motor based on different permanent magnets arrangements,and comparatively analyzes the impact of permanent magnets arrangements on the motor.Taking a Halbach magnetic field modulation permanent magnet motor as the object,this paper explores the key parameters of affecting the performance of this kind of motors by orthogonal test method.
