The Present Research and Development Situation of Permanent Magnet Spherical Motor of Multi-Dimensions

In this paper, the structures and characteristics of permanent magnet spherical motors of multi-dimensions are explained, and the present research progresses and development of permanent magnet spherical motors of multi-dimensions are summarized, the application prospects and developing-tendency are also discussed. A method of magnetic field analysis for one type of permanent magnet spherical stepper motor have been presented and the simulation results are showed.
