Embodiment Construction

[0029] exist figure 1 Shown in is used to represent each individual sub-conductor A1, B1, C1, D1, E1, F1, G1, H1, I1, J1, K1, L1 of the wave winding 100; A2, B2, C2, D2, E2, F2 , G2, H2, I2, J2, K2, and L2 are connected into a circuit diagram of conductors LE1, LE2, LE3, LE4, LE5, LE6, LE7, LE8, LE9, LE10, LE11, and LE12. The wave winding 100 is aimed at the motor 300 (not in figure 1) each phase W, V, U has four conductors LE1, LE2, LE3, LE4, LE5, LE6, LE7, LE8, LE9, LE10, LE11, LE12 interconnected in a parallel circuit.

[0030] Each conductor LE1, LE2, LE3, LE4, LE5, LE6, LE7, LE8, LE9, LE10, LE11, LE12 is respectively composed of two sub-conductors A1, B1, C1, D1, E1, F1, G1, H1, I1, J1 , K1, L1; A2, B2, C2, D2, E2, F2, G2, H2, I2, J2, K2, L2 constitute a series circuit. Such as figure 1 Said, for example, phase U can consist of four conductors LE1 , LE2 , LE3 , LE4 connected in parallel. Conductor LE1 may consist of a series circuit of two sub-conductors A1 and B2. ...

Abstract

To improve a wave winding set with a stator for a motor and to reduce voltage difference of a stator groove, each conductor of at least two connected conductors in a parallel-connection circuit is combined by a serial-connection circuit formed by at least two sub-conductors without reduction of copper filling compactedness or extra insulation material disposed in the stator groove.

Description

technical field [0001] The invention relates to a wave winding for a stator of an electric machine, wherein the wave winding is configured to be arranged in a series of stator slots arranged in the circumferential direction of the stator and has at least two for each phase of the electric machine Conductors connected to each other in a parallel circuit. [0002] In addition, the invention also relates to a stator and a motor. Background technique [0003] Care should be taken during the manufacture of the motor that the voltage difference between adjacent conductors in the stator slots should be as small as possible, because otherwise there would be a voltage load on the conductors or conductors during operation of the timed converter source. Partial discharge in the insulating material between. Such partial discharges may damage or even destroy the insulation system of the motor over the lifetime of the motor. [0004] In order to reduce the voltage difference, it is kno...
