双层远极比变极方案及单、双层远极比变极方案的比较

Two-layer Pole-changing Design ofWindings with Wide Pole Ratio and ItsComparison with Single-layer Pole-changingDesign of Windings with Wide Pole Ratio

本文以72槽4/32极绕组为例介绍了远极比变极绕组的双层结构方案,并把它与单层结构进行了比较。结果表明,双层结构的谐波含量比单层结构的要低,双层结构的磁密比值比单层结构的稍低。

The two-layer design of pole-changing windings with wide pole ratio, with 72 slots 4/32 poles winding as example, is proposed, and its comparison with single-layer design is also given. The result shows that harmonic contents of the two-layer design is less than the single-layer design, and magnetic flux density ratio of the two-layer design is slightly less than the single-layer design.
