摘要
基于大功率直线推进的要求,设计了一种新型十二相双边长定子直线感应电动机,介绍了十二相直线感应电动机的绕组结构。在此基础上,推导了十二相双边长定子直线感应电动机的ABC坐标系数学模型,分析了由电机各相端部绕组空间相对位置决定的十二相直线感应电动机端部漏感的不对称规律,并与多相旋转电机端部漏感的规律进行了对比分析;建立了仿真模型,对电机的电磁性能进行了计算。仿真实验证明了该数学模型的正确性。
To meet the requirement of the high-power linear propulsion system, this paper designs a novel twelve-phase linear induction motor （LIM） with double-sided long stators, and presents its winding construction. On this basis, a mathematical model of ABC coordinates for this novel motor is derived, which is used to analyze the asymmetry of the end-winding leakage inductance in the twelve- phase LIM with double-sided long stators, which is caused by the relative space position of each phase end-winding in the motor, and compare it with the asymmetry of the end-winding leakage inductance of the multi-phase rotating motor. Thus, a simulation model of the motor is established. The model is used for calculating the electromagnetic properties of the motor. The simulation results prove that the mathematical model is correct.
