Abstract：With the rapid development of the global automobile industry in recent years and the gradual shortage of petroleum resources，China's automobile industry is also facing daunting challenges. The rise of new energy vehicles is the general trend. One of the core components of electric vehicles is the electric motor. The permanent magnet motor has the advantages of large torque，high power density，large starting torque，good force performance indicators，high efficiency and energy saving，simple structure，and high reliability. The purpose of this paper is to carry out parameter design and simulation analysis according to the performance requirements of permanent magnet drive motors for electric vehicles，so that the design of the motor itself takes into account the driving conditions of electric vehicles，so that the motor can better meet the requirements of driving vehicles.
