Stator components and motors

Abstract

The invention discloses a stator assembly and a motor. The stator assembly includes a stator core and a stator winding. The stator core has a plurality of stator slots, and the plurality of stator slots are distributed along the circumferential direction of the stator core. Each stator slot has r slot layers, and the r slot layers are along the Arranged along the radial direction of the stator core. The first winding of each phase of the stator winding includes a first winding part and a second winding part connected end-to-end, the first winding part includes the first span section to the sixth span section, and the second winding part includes the seventh span section segment to the twelfth jump segment. The second winding of each phase of the stator winding includes the third winding part and the fourth winding part connected end to end, the third winding part includes the thirteenth span section to the eighteenth span section, and the fourth winding part includes the tenth Nine jumps to twenty-fourth jumps. According to the stator assembly of the present invention, the stator winding adopts a plug-in type forming method, and the arrangement method is simple and convenient to realize, and it is convenient for users to adjust the circuit.

Description

technical field [0001] The present invention relates to the technical field of motors, in particular, to a stator assembly and a motor. Background technique [0002] In related technologies, the armature connection method of the rotating electrical machine adopts a wave-winding method, that is, wave-winding from the outermost layer to the innermost layer, and then reverse wave-winding to the outermost layer. This armature connection method and implementation method, no matter from the analysis of the manufacturing process or from the mass manufacturer, there are too many types of flat wire armatures to be produced, and both ends of the axial direction need to be welded, and there are many solder joints. In addition, it is difficult to fix the flat wire accurately after it is rolled off the production line, resulting in high production cost and difficult manufacturing process. From the perspective of electrical connection, the wave winding method has a high voltage differenc...

Problems solved by technology

This armature connection method and implementation method, no matter from the analysis of the manufacturing process or from the mass manufacturer, there are too many types of flat wire armatures to be produced, and both ends of the axial direction need to be welded, and there are many solder joints. In addition, it is difficult to fix the flat wire accurately after it is offline, resulting in high production cost and difficult manufacturing process

From the perspective of electrical connection, the wave winding method has a high voltage difference between different layers in the same slot. When used under high voltage, it is easy to break down between layers, resulting in a short circuit and causing the motor to fail.
