永磁直流电动机磁通改变后的绕组设计

The Permanent-magnet DC Motor Winding Design after the Change of Flux

遵照永磁直流电动机工作特性随磁通量和电枢导体数变化的规律 ,论述了保持机械特性额定运行点不变时 ,磁通量变大后电枢导体数变化倍数的计算方法 ,并归纳为一个计算公式 ;同时分析了电机其它工作特性因此而改善的程度 。

Based on rule of the permanent-magnet DC motor work characteristics variation caused by the flux and the number of armature conductors,this paper discusses the armature conductors alteration multiple calculation for holding the rated working point in mechanical characteristics after the change of flux.Only one formula is needed to realize the calculation.The improvements of other work characteristics are also analyzed.The relative value schema method and formula used in the paper adapt every motor specification.
