Abstract: Aiming at the existing technical problems and future development trend of high-power locomotive drive system, the power mode of permanent magnet direct drive traction motor was proposed. According to the overall technical requirements,the design difficulties and key technologies of high-power locomotive direct drive traction motor,were researched two water-cooled permanent magnet direct drive traction motors were developed for high-power locomotive, andtests were carried out. The test results show that the motor meets the requirements of high-power locomotive drive system and verifies the feasibility of the design. It provides a reference for the application of permanent magnet direct drive technology in high-power locomotive.

Key words: high-power locomotive, permanent magnet direct drive, traction motor, driving system
