Abstract：The operation characteristics of high power density motor are introduced. The design is presented from the three aspects of electromagnetic design, mechanical process and cooling method with squirrel cage asynchronous motors and permanent magnet synchronous motor in electric vehicles. The improvement measures are verified with the motor test. The proposed design process can provide very good reference value for motor designers.
