Stator components and motors

Abstract

The invention discloses a stator assembly and a motor. The stator assembly has a plurality of stator slots, the first span section is from the rth layer of the i-th slot to the a-th layer of the i-th slot, and the second is from the a-th layer of the i-th slot to the a-th layer of the (i‑5) slot The jumping section, from the (i‑5)th slot a layer to the (i‑11) slot r layer is the third jumping section, from the nth slot r layer to the (n‑6) slot a The layer is the fourth jumping section, from the (n-6)th slot layer a to the (n-12)th slot r layer is the fifth spanning section, from the i'th slot r layer to the i'th slot The a-th layer is the sixth span section, from the i'th slot a layer to the (i'‑7) slot a layer is the seventh span segment, from the (i'‑7) slot a layer to The rth layer of the (i'‑13) slot is the eighth spanning section, and the rth layer from the n'th slot to the ath layer of the (n'‑6) slot is the ninth spanning segment, from the (n'th) -6) The a-th floor of the groove to the r-th layer of the (n'-12) groove is the tenth spanning section. According to the stator assembly of the embodiment of the present invention, the stator winding is arranged in a superimposed winding manner, and the arrangement is simple.

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.
