反向法变极绕组方案排列中的对称叠加原理

On the Principle of Symmetrical Superposition for 3-Phase Windings with Pole-Changing by Current Reversal

论述了反向法变极绕组方案排列中的对称叠加原理，及与之相关的对称位移原理，指出若干个对称方案叠加合成后仍为对称方案，应用这种方法可得到其他方法难以得到的新方案，通过实例进行了说明。

The principles of“symmetrical superposition”and“symmetrical displacement”are de-scribed and design methods are developed which enable a new 3-phase pole-changing windingwith current reversal in half of the phase-winding to be obtained.The methods proposed arecapable of giving a symmetrical winding which is not easily achieved by other methods avail-able. Examples of a 72 slots 6/8-pole winding are given.
