The invention relates to a three-layer winding motor stator variable-pole speed change method and relates to a method applied to a motor stator. A motor control system of the variable-pole speed change method comprises a three-layer winding motor stator, a phase-shifting element and control switches. An inner coil, a middle coil and an outer coil are arranged in the three-layer winding motor rotor, three layers of windings comprise one common working winding and two independent starting windings, and a centralized winding is adopted so that the efficiency of a motor can be improved. Accordingto the variable-pole speed change method, the three control switches carry out variable-pole control on the first working winding, the second working winding, the low-rotation-speed starting winding and the high-rotation-speed starting winding, that is, a simple control circuit achieves single-phase asynchronous motor variable-pole speed change. The working windings adopt a double-power design, low-power output is achieved at low rotating speed, and high-power output is achieved at high rotating speed, so that the requirement for energy conservation is met.

technical field [0001] The present invention is a three-layer winding motor stator pole-changing method, which relates to a method applied to the motor stator, in particular to a method applied to single-phase asynchronous motors, using three-layer stator windings, by changing the three-layer stator windings The connection method realizes the method of pole-changing and speed-changing. Background technique [0002] The motor stator winding coil is divided into two structural types: distributed winding and concentrated winding. Most asynchronous motors use distributed windings, while brushless DC motors (BLDC) and permanent magnet synchronous motors (PMSM) use centralized windings. The processing technology of distributed winding is complicated, and the processing technology of centralized winding is simple. The interphase insulation strength of centralized winding is higher than that of distributed winding. The winding end length of the concentrated winding is shorter tha...
