Problems solved by technology
At present, the optimization design research on the stator double-winding asynchronous motor power generation system is only carried out for the three-phase stator double-winding asynchronous power generation system. It does not involve the volume and weight optimization of the generator body, and there is no research on the use of multi-phase stator double windings. Structure and harmonic injection non-sinusoidal power supply technology to optimize the volume and weight of the generator
