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 first winding of each phase of the stator winding includes a first winding part and a plurality of second winding parts. The first winding part includes a first jumping segment to a fourth jumping segment, The second winding part includes a fifth jumping section and a sixth jumping section, and the second winding of each phase of the stator winding includes a third winding part and a plurality of fourth winding parts, and the third winding part includes a seventh jumping section From the tenth jumping segment, the fourth winding part includes the eleventh jumping segment and the twelfth jumping segment. According to the stator assembly of the present invention, during the winding process, by setting the pitches of multiple jumping sections to be different from those of other jumping sections, the potential vector of the stator slot can be balanced, and the potential phase of the slot moment angle can be suppressed. Angle difference, so that the potential balance between the circuit windings can be realized, the internal circulation of the stator winding can be suppressed, the harmonic electromagnetic excitation generated by the circulation can also be suppressed, and the vibration of the motor can be reduced.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a stator assembly and a motor. Background technique [0002] In the related technology, the stator assembly of the motor is wave-wound, from the outermost layer to the innermost layer, and then the reverse wave is wound to the outermost layer. From the analysis of the manufacturing process and the mass manufacturer, the flat wire armature that needs to be produced There are many types, and both ends of the axial direction need to be welded, and there are many solder joints. In addition, after the flat wire is offline, it is difficult to fix it accurately, the production cost is high, and the manufacturing process is difficult. From the analysis of the electrical connection, the wave winding form has a high voltage difference between different layers in the same slot. When used under high voltage, the layers are easily broken down, resulting in a short circuit and causing the motor...
