Abstract
A single-phase induction motor includes a main winding, an auxiliary winding, a run capacitor, and a subsidiary start device. The auxiliary winding is configured such that the number of turns of the auxiliary winding, through which a current flows, varies according to the operating mode of the motor. When the motor starts, the number of turns of the auxiliary winding, through which a current flows, is reduced, thereby increasing the start efficiency of the motor. When the motor runs in normal mode, the number of turns of the auxiliary winding, through which a current flows, is increased, thereby increasing the operational efficiency of the motor.
Claims15
A single-phase induction motor comprising a main winding, an auxiliary winding, a run capacitor, and a subsidiary start device,
- wherein the auxiliary winding is configured so that the number of turns thereof, through which a current flows, varies depending on operating states of the motor in order to increase start and operational efficiencies of the motor.
A single-phase induction motor comprising:
- a rotor;
- a stator having a plurality of slots formed therein;
- and main and auxiliary windings being formed on the stator through the slots,
- wherein the auxiliary winding is installed in the form of two parallel coils on the stator through the slots, and the auxiliary winding comprises a first auxiliary winding portion and a second auxiliary winding portion, the second auxiliary winding portion being formed by additionally winding a coil from one end of the first winding portion.
