Abstract:

A type of five-phase fault-tolerant permanent magnet motor which was used for electromechanical actuator was studied. The design thought of fault-tolerant motor was analyzed, and the motor was designed preliminarily according to the indexes. In order to optimize its structure parameters, a finite element simulation model of the motor was built and the influence of slot opening and skew slot on motor’s performance was investigated. A prototype experiment was performed on the optimized motor, and the experimental results verify the correctness of the design.

Key words: fault-tolerant permanent magnet motor, finite element simulation, skew opening, skew slot
