Embodiment Construction
[0019] The present invention will be further described in detail below through the specific examples, the following examples are only descriptive, not restrictive, and cannot limit the protection scope of the present invention with this.
[0020] A stator core structure of an outer rotor permanent magnet motor, see figure 1 , figure 2 , image 3 , the stator core is a multi-rack structure with reverse slots, that is, the edges of the slots of the adjacent teeth of the stator core are connected by connecting bars 2, and the adjacent stator yokes 3 are made into the same slot gap , the winding 4 is rewound from the open stator yoke to the multi-rack stator tooth 1, and after being bent into a circular stator, the stator yoke is closed, and the air gap side of the stator teeth is connected to form a closed slot structure.
[0021] A method for rewinding a stator winding of an outer rotor permanent magnet motor, the steps of which are:
[0022] (1). The stator core connects th...
