Stator assembly and motor

Abstract

The invention discloses a stator assembly and a motor. The stator assembly comprises a stator core and a stator winding. The stator core is provided with a plurality of stator slots which are distributed along the circumferential direction of the stator core. Each stator slot is provided with r slot layers which are arranged along the radial direction of the stator core. Each phase of first winding of the stator winding comprises a first winding part and a second winding part which are connected in an end-to-end way. The first winding part comprises first to sixth spans, and the second windingpart comprises seventh to twelfth spans. Each phase of second winding of the stator winding comprises a third winding part and a fourth winding part which are connected in an end-to-end way. The third winding part comprises thirteenth to eighteenth spans, and the fourth winding part comprises nineteenth to twenty-fourth spans. According to the stator assembly, the stator winding uses the plug-informing mode, the arrangement mode is simple, the implementation is convenient and the line adjustment can be facilitated for the user.

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...

AI Technical Summary

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.
