摘要
特殊结构电机的特性分析,一般需要用计算机仿真技术对电机的数学模型求数值解,而绕组的自感和互感参数则是建立电机数学模型的基础。本文介绍了两种简单易行的测定电机绕组自感和互感参数的方法——静测法与旋转电势积分法(亦称动测法)。文中给出了一台具有不均匀气隙、不对称六相绕组结构的新型方波同步电机的应用实例,并对该电机的计算机仿真结果和实测波形作了比较。
Computer simulation is usually needed for performance analysis of electrical machine with special structure. However, to solve the mathematic model of electrical machine needs to know all the reactances of machine windings. This paper introduces two simple and useful methods to determine self and mutual reactances of machine windings-static and dynamic measurement methods. The paper gives a practical application example for a new type of square wave synchronous machine with non-uniform air gap and asymmetric six phase winding structure. The waveform comparison of simulation with measurement results is also presented in the paper.
