隐极迭片转子同步电动机启动特性计算机仿真
Computer Simulation for Asynchronous Starting Performance of Synchronous Motor with Laminated Cylindrical Rotor
【摘要】 本文提出了用多回路法来计算隐极迭片转子同步电动机的启动特性,包括各回路的电流;导出了用于似稳态和动态分析的数学模型;提出了用转子电阻分布系数来描述转子不对称性的方法.文中以一台22kW电动机为例,对不同阻尼绕组情况下的不同电阻分布系数γ进行了计算和分析,结果表明当γ接近零时,其启动特性接近于异步电动机的启动特性.实验还表明,计算结果与实验结果吻合较好.
【Abstract】 A method for calculation of the starting performance of a synchronous motor with laminated cylindrical rotor by the multi-loop technique is described. It is suitable for calculating both the asynchronous steady-state and dynamic process as well as the current distribution in damper bars. A method for presenting the asymmetric degree of the rotor is proposed. Computational and test results of the starting performance of a 22 kW synchronous motor are given.
