摘要
提出一种将飞轮惯性储能和电磁耦合器原理相结合的双转子感应电机(dual rotor induction motor,DRIM)。DRIM采用外转子(主动转子)储能、内转子(从动转子)驱动负载的结构。首先介绍该电机的结构特点与工作机理,然后基于有限元法分析DRIM驱动模式下瞬态工作特性,讨论主动转子储能转速与励磁电压对DRIM输出性能的影响,最后通过样机实验对电机原理及运行特性的理论分析进行验证。结果表明,DRIM具有电机励磁功率与输出功率之比小,电机结构及控制方式简单的特点,为大功率机械负载瞬时加速系统提供一种新型储能驱动集成电机方案。
A novel dual-rotor induction motor(DRIM)applied for energy storage and driving was proposed in this paper.It was based on electromagnetic coupling and fly-wheel energy storage mechanism.DRIM adopted dual-rotor structure,which consisted of an external rotor(master rotor)for energy storage and an internal rotor(slave rotor)for driving load.The structure feature and operation mechanism of DRIM had been presented firstly in this paper.Then the transient working characteristics of DRIM operating on driving model had been analyzed by finite element method(FEM).And the influence of both energy storage speed of master rotor and exciting voltage on DRIM working characteristics had also been studied.Finally the feasibility of DRIM and theory analysis results of the working characteristics had been verified by experiment of a prototype.The theory study and experiment results have demonstrated that DRIM is characterized by low ratio of required exciting power to output power and simple structure and control method,all of which make DRIM be a novel energy storage and driving integration motor scheme for the instantaneous large power mechanical load accelerating system.
