【Abstract】 This paper proceeds the first step investigation for energy consumption braking and of three-winding single phase capacitance motors with SemihexTM-connected,and the simulation of the proposed three kinds of line connecting method is also investigated.The mathematics models of three-winding single-phase capacitance motors with the SemihexTM-connected in stationary d-q coordinate frame have been established to get the transient characteristics.MATLAB language is used to develop the computer simulation program.The program is applied to emulate energy consumption braking transient process of three-winding single-phase capacitance motors with SemihexTM-connected drive ventilated machine load through example.Samulation results are also analyzed here.The results of simulation show that three-winding single-phase capacitance motors with SemihexTM-connected drive ventilated machine load can arry out energy consumption braking to realize fast stopping.The capacitance number of changes can regulate system braking stopping time.The energy consumption braking system can realize accurate stopping.更多还原
