Design and optimization of the jet cooling structure for permanent magnet synchronous motor
Permanent magnet synchronous motor (PMSM) is widely used in electric vehicles due to its high power density and wide speed range. However, when operating under long-term heavy load conditions, PMSM is prone to heat accumulation. It’s difficult to cool the motor with existing indirect cooling structures efficiently, which may lead to its high temperature and result in winding burnout or even permanent demagnetization of the magnets. In this paper, a novel cooling structure based on jet cooling is proposed to reduce the operating temperature of the PMSM efficiently and improve its stability. The temperature field model, which accounts for the influence of end windings, is developed to analyze and optimize the parameters of the jet cooling structure, leading to the determination of an optimal parameter set. By exploring the cooling effects of motors with different cooling structures under stable, extreme and mixed cycle operating conditions, it is proved that the jet cooling structure designed in this paper can effectively reduce the temperature of the motor and ensure its reliable operation. The results show that with the influence of the jet cooling structure designed in this paper, the maximum temperatures of the rotor and winding are reduced by 35.2℃ and 44.5℃ respectively.
