摘　　要：为了进一步提升矿用集中绕组永磁电机的功率密度和散热能力,提出一种冷却水管与绕组并绕的新型绕组冷却结构。以一台315 kW集中绕组永磁电机为例,首先,通过合理的等效与假设,建立了电机的三维模型,基于计算流体力学(CFD)方法对电机进行温度场分析。其次,分析了不同的并绕方式以及相同并绕方式下不同的进水口进水速度对电机散热的影响,确定了最优散热方式。仿真分析表明冷却水管与绕组并绕的方式有效提高了散热能力。In order to further improve the power density and heat dissipation capacity of the mine-used concentrated winding permanent magnet motor,a new winding cooling structure with cooling water pipe and winding wound parallelly is proposed.Taking a 315 kW concentrated winding permanent magnet motor as an example,a three-dimensional model of the motor is established through reasonable equivalence and assumptions,and the temperature field of the motor is analyzed based on computational fluid dynamics(CFD)method.The effects of different parallel winding methods and different inlet speeds under the same parallel winding method on the heat dissipation of the motor are analyzed,and the optimal heat dissipation method is determined.The simulation analysis shows that the parallel winding of cooling water pipe and winding effectively improves the heat dissipation capacity.
