In this paper, the distribution of magnetic field and the reaction of armature can be analysed using Ansoft. The parameter of motor can be regulated through simulation. This paper analyses the theory of multi-phase and multi-pole high power density motor, the result of simulation is given. Key words: high power density; simulation of motor; permanent magnet motor 1．引 言 ……
