Based on expounding the differences of working principle between permanent magnet synchronous traction motor and asyn- chronous traction motor and the description of stability for permanent magnet material, this paper analyzes the specificity of permanent magnet synchronous traction motor, including low loss of rotor, overload capacity, pole number selection, environmental adaptability, control mode, and the faults caused by irreversible demagnetization and the fact that magnetic fields cannot be adjusted. The relative measures in motor design are also proposed. It provides a reference for the design of permanent magnet synchronous traction motor.
