摘　　要：在初步探索了对△接法的三绕组单相电容电动机的电气制动方式基础上,对直流制动和交流制动两种接线方式进行仿真研究。建立起△接法三绕组单相电容电动机在α-β坐标系下的瞬态数学模型,编写计算机仿真程序,通过对电动机带通风机负载时的实例,对所提出的接线方式下的电气制动的瞬态过程进行仿真分析计算,给出了仿真特性曲线。仿真结果表明:直流制动有明显的优越性;直流制动可以实现准确停车。Investigating for the direct current braking and the alternating current braking of three - winding single - phase capacitance motors with delta - connected,the two kinds of connecting the line method were put forward. The mathematics models of three - winding single - phase capacitance induction motors with the delta - connected in α-β coordinate frame were used to get the transient characteristics. The program was applied to emulate DC braking and AC braking transient process of three - winding single - phase capacitance motors with delta - connected take ventilated machine load through example. Emulation results were also studied here. The results of simulation showed that DC braking has obviously superior, and that DC braking system can realize accurate stopping.
