[0002] Water cooling (oil cooling) permanent magnet synchronous motor is widely used in modern industry due to its high efficiency and high power density characteristics, especially in occasions requiring high performance and high reliability. However, as the working temperature rises, the performance of permanent magnet material will decrease significantly, and even irreversible demagnetization phenomenon may occur, thereby affecting the normal operation and service life of the motor. Therefore, the effective heat dissipation of the current water cooling permanent magnet motor relies on the external water driven by the water pump through the internal pipeline of the water cooling (oil cooling) permanent magnet synchronous motor, and the low temperature of the external water is used to heat treat the water cooling (oil cooling) permanent magnet synchronous motor itself.
