Embodiment Construction
[0022] The present invention will be further elaborated below through specific embodiments.
[0023] The AC motor stator winding unitized parallel winding structure of the present invention, the structure of the AC motor stator adopts a centralized winding structure and a star connection structure in which each phase winding branch is independent of each other and each phase winding branch is connected in parallel; specifically: multi-stage multi- The number of phases of a phase AC motor is m, the number of stator slots is Z, the number of pole pairs is p, and Z can divide m; the stator slots are divided into Z / m units, each unit contains m teeth, and m teeth A parallel branch of m phases is respectively wound, and the tail ends of the parallel branches wound by m teeth on each unit are connected to form a neutral point of a star connection, and the Z / m units form a Z / m An independent unconnected neutral point; and the first ends of each phase winding of each unit are respecti...
