摘要
为解决传统混合动力汽车用双转子电机同心永磁式结构存在散热不良和磁场耦合等问题,将两个同尺寸开关磁阻电机通过联轴器机械连接起来,设计成一种新型分体式开关磁阻双转子电机(Split Switched Reluctance Dual-rotor Motor,SSR-DRM),分析其工作原理和多工况运行模式,进行参数设计、建模以及电磁静态和瞬态仿真,从磁力线分布、磁密、瞬态转矩与空载反电势等对比分析设计和仿真。结果表明:SSR-DRM的主、副电机在560 V直流电压下,额定转矩为80 N·m,额定转速为3 000 r/min,额定输出功率为25 kW,满足设计要求。
There are some problems such as bad heat dissipation and electromagnetic coupling for the traditional dual-rotor motor of hybrid electric vehicles. Two SRMs of same size are mechanically connected through a coupling to form a dual-rotor motor with two rotors and one stator. A split switched reluctance dual-rotor motor(SSR-DRM) is innovatively designed. The working principle and multi-operating mode of SSR-DRM are analyzed, and the parameters design, modeling and electromagnetic simulation are implemented. The parameters of design and simulation are compared and analyzed from the aspects of magnetic line distribution, magnetic density, transient torque and no-load back EMF. The results show that under 560 V DC voltage, the split switched reluctance dual-rotor motor’s rated torque is 80 N·m, rated speed is 3 000 r/min and rated output power is 25 kW. Simulation results meet the requirement of design.
