【 摘 要 】

Brushless doubly-fed machine (BDFM) has advantages of brushless reliability and low frequency conversion capacity. It has a broad application prospect in AC speed regulation and direct drive wind power generation system. In this paper, winding arrangement and slot electromotive force star diagram of stator with different pole numbers are analyzed and studied comprehensively. When the number of slots per pole and phase is different, we get the winding wire insertion rule. These rules are of great significance for further design and application of multipole BDFM.
