交流电机转子绕组中复合线圈连接原理研究

An Investigation on Connections for Composite Coils Used in Partially Non-Inductive Windings in Pole-Changing Motors

复合线圈是一种可用来改善交流电机起动性能的新型转子线圈，对其连接问题，归纳为自然等位连接和强制等位连接进行了分析，并通过实例进行了说明。

The principle of the connecting method and conditions required for composite coil8 con-sisting of two parallel subcoils different in the number of turns are described. The new typerotor coils are used in pole-changing wound-rotor induction motors to give both high startingtorque and good efficiency. An example is given.
