Problems solved by technology

[0002] In related technologies, single-phase motors mostly use tap speed regulation, and a speed regulation winding is wound on the stator. The speed regulation winding of each gear needs to be composed of at least two coils with different spans, such as figure 1 As shown in the schematic diagram of winding distribution, some winding slots contain four layers of coils. On the one hand, the embedding process is more complicated; During the process, there are potential failures such as disconnection and burn-in

Abstract

The invention provides a single-phase adjustable-speed motor. The single-phase adjustable-speed motor comprises a main winding, an auxiliary winding and at least one adjustable-speed winding, whereinthe main winding comprises a main long-distance coil and a main short-distance coil, and the main winding is used for controlling continuous running of a motor; the auxiliary winding comprises an auxiliary long-distance coil and an auxiliary short-distance coil, and the auxiliary winding is used for controlling starting running of the motor; each adjustable-speed winding comprises multiple adjustable-speed coils; the main long-distance coil and the auxiliary long-distance coil stride over a first number of winding teeth to be embedded, the main short-distance coil and the auxiliary short-distance coil stride over a second number of winding teeth to be embedded, the adjustable-speed coils in each adjustable-speed winding stride over a first number of winding teeth to be embedded or stride over a second number of winding teeth to be embedded, so that 3 layers of coils are distributed in each winding groove at most. By means of the technical scheme, the complexity degree of the preparation process can be reduced, the dropping difficulty can be reduced, and the operation performance of the single-phase adjustable-speed motor is improved while the preparation cost of the single-phase adjustable-speed motor is reduced.
