Harmonic analysis and using the harmonic in the design of the windings of the alternating current motor

文章以大小双星型绕组为例,着重介绍了谐波起动感应电机的起动性能及原理,给出了用于编制程序的数学模型与算法,这不但易于实现新型绕组的设计软件,还可以获得常用电机正规绕组的自动分槽与普适的磁势谐波分析程序,并根据槽号相位表证明60°相带绕组的优越性。

The starting characteristic and principle of a new-type asynchronous motor started by harmonics are described by taking the YmYn/Ym windings in both the stator and the rotor as the example. The mathematic model and algorithm are presented so that the program for the design of the novel windings can be easily deduced. This study is also beneficial to the automatic slotting of the stereotyped windings of induction motors and the analysis of harmonics of flux in all sorts of windings. On the basis of the s-vector table,the 60-degree phase belt winding for alternating current machines is proved as the optimal one in all kinds of stereotyped windings.
