The development of a 235 kW totally enclosed permanent magnet synchronous motor for next-generation suburban trains is presented in this paper. A novel cooling structure was proposed, and its effectiveness was verified in a temperature rise test. An internal permanent magnet structure optimized to increase reluctance torque was used to reduce the maximum current. The results of testing and calculation show that this new motor can reduce the energy consumption of the train by 12% and acoustic noise emission by 7 dB.
