The Starting Performance Research on the Novel Single-phase Induction Motor

To ensure the starting performance of the single-phase induction motor with three parallel-connected windings, the transient performances and starting methods are studied in this paper. At first, the transient mathematical model of the motor is established according to the electromagnetic relations, and the simulation analysis is performed. Then two starting methods are proposed and studied. The first is starting with two additional starting capacitors. The second is the improvement of the first and has only one additional starting capacitor. By the simulation analysis, it is proved that both of them have good starting performances, and the starting method with one starting capacitor can simplify the starting circuit.
