This paper concerns the analysis and optimization of a permanent magnet linear synchronous motor. The motor consists of moving ironless coils and a stator with novel double-side Halbach array. Some characteristics of the linear motor were investigated. The dimensions of the novel Halbach magnet array were optimized. The optimization was verified by finite element method.

This paper describes the speed regulation of a magnetic gear integrated permanent magnet synchronous motor. The operating principle of the motor is discussed and the torque transmission is analyzed using finite element method; hence the motor model is established. The speed regulation is analyzed under vector control, and the simulated results verify the feasibility of speed regulation control.
