Abstract：The first chapter describes the significance and purpose of the study, reviews the long history of the development of the motor, also explores the possible direction of the motor in the future, and introduces the constant torque and constant power speed control methods of the speed regulating motor。 The basic working principle of the permanent magnet synchronous motor and the introduction of the permanent magnet material in the rotor are also discussed。 The working characteristics of the permanent magnet synchronous motor are also discussed。 The magnetic circuit structure of the rotor of the permanent magnet motor is analyzed, and several different kinds And its characteristics and uses are described。 The design characteristics and main dimensions of the permanent magnet synchronous motor and 

the selection of the rotor magnetic circuit structure are described, and the basic steps of the design of the permanent magnet synchronous motor are established。 According to the data given in the task book, the main dimensions of the permanent magnet synchronous motor, the stator and rotor design, the stator winding calculation, the calculation of the rotor magnetic circuit, the parameters and the working characteristic are determined by using the electromagnetic correlation calculation formula。 Finally, the performance of the motor is calculated by using the Ansoft software。 The power factor is 0。97 and the efficiency is 95。5%。 The calculated results are basically the same as the manual calculation results, which further validates the accuracy of the motor design calculation。
