Highspeed motor had some merits such as high power density, contact volume, smaller weight, and could directly drive load, so it had wide application prospects in the fields of aviation, new energy and precision manufacture. The bearingless permanent magnet motor was used in highspeed drive system. Based on the introduction of mathematical model, the design methods of highspeed bearingless permanent magnet type motor were principally discussed. The electromagnetic and mechanical design of a rated speed 8 000 r/min, speed range 0~60 000 r/min, 2 500 W highspeed bearingless permanent magnet motor was accomplished. Both the electromagnetic and dynamic performances of the motor were optimized based on finite element method. The simulation and experimental research results showed that the design method of highspeed bearingless permanent magnet motor proposed was correct and feasible.
