Abstract: Capacitor-run single-phase induction motors have a wide application in water pumps,fans and ventilating machines.This paper designed a capacitor-run single-phase induction motor for the water pump,analysed its performances based on Maxwell,and then established its two-dimensional finite element model,analysed the transient magnetic field and dynamic performances.The results show that the design is reasonable and can be put into practice.
