摘　　要：传统的无刷双馈电机特殊笼型转子存在谐波含量大,导体利用率低的问题,而绕线转子接法灵活,有望改善转子性能,从而提高电机的运行性能。本文提出了一种基于"极幅调制"原理的无刷双馈电机绕线转子的排布方法,该方法可以借鉴交流绕组的变极理论,并通过经典的"对称轴线法"来具体实现,具有概念清晰,设计灵活的优点。给出了该排布方法的基本原理和实现步骤,并结合一个72槽8/4极的设计方案来具体说明。The traditional special-cage rotor of BDFM has a disadvantage of high harmonic content and low utilization ratio of conductor,while the wound rotor has a diverse configuration and is supposed to improve the performance of BDFM.This paper presents a novel design method for wound rotor of BDFM based on theory of pole-amplitude modulation.The design can be implemented through the 'Method of Symmetrical Axis' of pole-changing theory and has some advantages of clear conception and flexibility.The basic principle...
