| 摘 要： | 在不考虑边端效应的前提下,分析了一种无槽双边长定子直线异步电动机的二维磁场分布,在此基础上推导出电动机的相关电感参数和电磁推力计算公式.将解析计算结果与有限元计算结果进行比较分析,证明了理论分析的正确性.为了分析纵向边端效应对这种类型电动机性能的影响,还比较了考虑纵向边端效应和不考虑纵向边端效应两种情况下电动机的电磁推力,为这种新型直线电动机的优化设计提供了理论依据.

| Abstract: | This paper analyses two dimension magnetic field of a slotless long stator double-sided linear induction motor (DSLIM), without considering the end effects and transverse edge effects. Some inductance parameters and electromagnetic force are derived. Finite element analysis (FEA) results verify the validity of the calculation approach. Two type of electromagnetic force are presented to show the influences of the end effects on the motor performance. It provides an optimal way to this novel type DSLIM. |
