摘　　要：对Y接法的三绕组单相电容电动机的电气制动(直流制动和交流制动)进行了初步探索,并就所提出的2种接线方式进行仿真研究.建立了Y接法三绕组单相电容电动机在静止α-β坐标系下的瞬态数学模型,编写计算机仿真程序,通过实例对电动机带通风机负载时在所提出的接线方式下的电气制动的瞬态过程进行仿真计算,给出了仿真特性曲线.对仿真结果进行了分析.仿真结果表明:Y接法三绕组单相电容电动机带通风机负载时可以进行直流制动和交流制动实现快速停车;通过改变直流电源电压的数值和电容的数值可以调节制动停车的时间;从节能的角度上看,直流制动有明显的优越性;直流制动可以实现准确停车.The first step investigates for DC braking and AC braking of three-winding single-phase capacitance motors with wye-connected is moved,put forward the two kinds of connecting the line method. The mathematics models of three-winding single-phase capacitance induction motors with the wye-connected in stationary α-β coordinate frame are established to get the transient characteristics. MATLAB language is used to develop the computer simulation program. The program is applied to emulate DC braking and AC braking transient process of three-winding single-phase capacitance motors with wye-connected take ventilated machine load through example. Emulation results are also studied here. The resuits of simulation show that three-winding single-phase capacitance motors with wye-connected drive ventilated machine load can proceed to DC braking and AC braking to realize fast stopping. The capacitance number of changes can regulate system braking stopping time. Seeing from the angle of the economy energy, the direct current braking is obviously superior. The direct current braking system can realize accurate stopping.
