Abstract To solve the problem of temperature rise caused by the high power density of high-speed permanent magnet synchronous traction motors, the temperature rise of various components in the motor is analyzed by coupling the
equivalent thermal circuit method and computational fluid dynamics. Also, a
cooling strategy is proposed to solve the problem of temperature rise, which is
expected to prolong the service life of these devices. First, the theoretical bases
of the approaches used to study heat transfer and fluid mechanics are discussed,
then the fluid flow for the considered motor is analyzed, and the… More >
