Stator assembly and motor

Abstract

The invention discloses a stator assembly and a motor. The stator assembly is provided with a plurality of stator slots. The first span is from the rth layer of the ith slot to the ath layer of the ith slot, the second span is from the ath layer of the ith slot to the ath layer of the (i-5)th slot, the third span is from the ath layer of the (i-5)th slot to the rth layer of the (i-11)th slot, thefourth span is from the rth layer of the nth slot to the ath layer of the (n-6)th slot, the fifth span is from the ath layer of the (n-6)th slot to the rth layer of the (n-12)th slot, the sixth span is from the rth layer of the i'th slot to the ath layer of the i'th slot, the seventh span is from the ath layer of the i'th slot to the ath layer of the (i'-7)th slot, the eighth span is from the athlayer of the (i'-7)th slot to the rth layer of the (i'-13)th slot, the ninth span is from the rth layer of the n'th slot to the ath layer of the (n'-6)th slot and the tenth span is from the ath layerof the (n'-6)th slot to the rth layer of the (n'-12)th slot. According to the stator assembly, the stator winding uses the mode of laminating wiring 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...

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.
