Delta, Y-shape winding wiring method of single phase motor and its circuit

Abstract

A phase winding in single-phase motor (SPM) is arranged to T1, T3 and T2, T4 parallel windings in two routes according to different pole phases by using bridge balance method (BBM). Then, the parallel windings are connected to winding TC, which is symmetrical to the parallel windings, in series. The winding in another phase is prepared according to steps: according to number of turns of shortchorded winding of concentric coil, carrying out bankwinding; then according to difference value of number of turns between polar distance winding and shortchorded winding, preparing a winding bank windedto position of electrodes. Through innovative arranging main winding of SPM, the invention raises wire carrying ratio 30%, and saves cost. Using BBM changes ciruit of SPM to 'delta-Y' equivalent circuit in three phases motor so as to raise efficiency and performance to top-level motor in 'delta-Y' connection from previous level lower than three phase simple motor.

Problems solved by technology

[0002] In the prior art, the single-phase asynchronous motor power supply is directly connected to the two-phase windings with a phase difference of 90° after being shunted by capacitors to alternately drive the magnetic current to obtain the magnetic field rotation of the motor; there are only two pole phases in the stator Electrode conversion drives the magnet, the phase belt angle is 90°, and the output of the auxiliary phase is insufficient, which together cause problems such as unstable rotation of the motor, small output, low efficiency, and large noise. The number of pole phases is small, and the concentric winding method is used to distribute the winding, resulting in a very low wire load rate of the winding, so that the single-phase capacitor motor of the existing general technology has a large amount of consumables and poor performance

It is complete, but it is flawed. The "Δ" circuit of the bridge combination cannot control the flat-sided triangle design required for the balance of the motor circuit, and cannot achieve the highest standard for smooth rotation of the motor; Compared with three-phase motor performance
