Description
Technical Field

Background
The winding design of the single-phase voltage doubling motor generally adopts a T-type circuit technology, namely, a main winding is divided into two sections (a main winding 1 and a main winding 2), and an auxiliary winding 3 is independently divided into one section. The main winding 1, the main winding 2 and the auxiliary winding 3 are connected in parallel to work at low voltage; in high voltage, the auxiliary winding 3 and the main winding 2 are firstly connected in parallel and then connected in series with the main winding 1 to form a T-shaped circuit for working, wherein Im1= Ia + Im2, and the main winding with Im1 measures current at high current, the main winding with Im2 measures current at low current and the auxiliary winding with Ia measures current (see a circuit schematic diagram of a single-phase voltage-multiplying motor with the attached figure 1 at high voltage). At present, the braking method in the industry adopts a two-way combination type of a main winding, and concentrated winding, wire embedding and shaping are carried out (such as a two-way combination device of the main winding (a device with an auxiliary winding removed) shown in figure 2). The main winding 1 is distributed on the left side of the motor stator in a concentrated mode, and the main winding 2 is distributed on the right side of the motor stator in a concentrated mode. It is known that, when the single-phase voltage-multiplying motor is at a high voltage, the working current of the main winding 1 greatly exceeds the working current of the main winding 2, and the magnitude relationship is Im1 (main winding 1 current) = Im2 (main winding 2 current) + Ia (secondary winding current), as shown in the schematic circuit diagram of fig. 1. The current Im1 of the main winding 1 on the left side of the motor stator is larger than the current Im2 of the main winding 2 on the right side, so that the magnetic pulling force on a rotor generated by the current on two sides of the motor stator is unbalanced, and the vibration and the noise of the motor are larger; and because the main winding 1 on the left side of the motor stator has large current and high temperature rise, and the main winding 2 on the right side of the motor stator has small current and low temperature rise, the motor design can only use the point with the highest temperature rise as the design basis, thereby increasing the cost.
