Abstract
In order to perform a comprehensive study on the ventilation characteristics of an induction motor rotor end's self-support components, and specify the relationship among its size, structure, motor loss and cooling performance, in this paper a 3D physical model of the rotor, stator and motor shell was established according to the characteristics of the total enclosed fan-cooled (TEFC) induction motor. Then the fluid field and temperature field of the TEFC induction motor was solved by combining finite volume method (FVM) and the basic principles of electric machine. By taking the rotor air friction loss and stator end windings temperature rise into consideration and comparing various solutions, the optimum solution to the length of the self-support components was determined, which provided a reference for the optimization of the motor rotor physical construction.
