【摘要】 对Y接法的高压感应电动机，提出将每相绕组分为四段的Y／Y接法反向一换相混合变极法，与每相绕组分为三段的换相变极法相比．用这种方法获得的变后极绕组有较高的绕组系数及可能有较小幅值的高次谐波．通过实例进行了说明．更多还原

【Abstract】 A new method transforming 3-phase windings into pole changing windings, which require that each phase winding is divided into four parts which remain connected together in one phase at the basic pole number and is applicable to high-tension voltage induction motors with Y connection, is presented. The new windings can have higher distribution factor and low-er magnitude of harmonics than conventional pole-changing windings with three parts in one phase. An cxample is given on a 10 / 8-pole machine.更多还原
