摘　　要：对三角形接法的三绕组单相电容电动机的交流制动的瞬态过程进行了初步探索和仿真研究。建立了三角形接法三绕组单相电容电动机在α-β坐标系下的状态空间瞬态数学模型,通过实例对电动机带通风机负载在提出的两种接线方式下的交流制动的瞬态过程进行仿真计算。仿真结果表明:三角形接法的三绕组单相电容电动机可以通过交流制动实现快速停车;改变电容的数值可以调节制动停车的时间;当电容一定时,可以在定子电路中串联电阻来限制制动过程中的电流和电磁转矩,调节制动停车的时间。The first investigation and simulation for AC braking of three-winding single-phase capacitance motors with delta-connection are put forward. The state space mathematics models of three-winding single-phase capacitance induction motors with the delta-connection in stationary α-β coordinate frame have been established. AC braking transient process of three-winding single-phase capacitance motors with delta-connection which take ventilated machine load is emulated through an example. The simulation results show that three-winding single-phase capacitance motors with delta-connection can proceed to AC braking to realize fast stopping; the capacitance number of changes can regulate braking stopping time; when capacitance is certain, can establish the resistance in stator circuit to limit the electric current and electromagnetical torque during the braking process, regulating braking stopping time.
