摘　　要：合适的冷却结构能够保证电机安全运行的同时,也能够简化电机设计。为有效控制无轭定子结构的轴向磁通电机的整体温升,提升其散热能力,基于非晶合金电机低损耗的特点,提出了一种在机壳上集成周向式散热叶片的外转子散热结构。通过流固耦合的方法,对该结构下的电机进行了温度场的分析,验证了该方案的可行性。对一台额定功率为20 kW的轴向磁通电机进行温升实验,实验结果证明了该散热结构的有效性。A suitable cooling structure can garantee the safe operation of the motor while simplifying the motor design.In order to effectively control the overall temperature rise of axial flux motors with yoke-less stator structure and enhance their heat dissipation capability,an external rotor cooling structure with circumferential heat dissipation vanes integrated in the housing was proposed based on the low-loss characteristics of amorphous alloy motors.Through the method of fluid-solid coupling,the temperature field of the motor under this structure was analysed to verify the feasibility of the scheme.The temperature rise experiments were carried out on an axial flux motor with a rated power of 20 kW,and the experimental results proved the effectiveness of this heat dissipation structure.
