Abstract:

A new fault-tolerant permanent magnet rim driven motor was studied in order to meet the needs of low noise and high security of underwater propulsion motor. The structural characteristics of the fault-tolerant permanent magnet rim driven motor and the influence of the main parameters on the motor performance were analyzed. The two-dimensional simulation model of the motor was carried out by ANSYS Maxwell to verify the magnetic flux density, back electromotive force, inductance and fault tolerance of fault-tolerant permanent magnet rim driven motor. It's proved that the fault-tolerant permanent magnet rim driven motor is fault-tolerant and has high-performance features.

Key words: fault-tolerant permanent magnet rim driven motor (FTPM-RDM), finite element, fault tolerance
