Problems solved by technology

However, due to the high hardness of the square conductor, it is difficult to twist, and the insulating varnish on its surface will be damaged when it is bent and twisted, and the insulation of the winding will be damaged, so the application of the square conductor in the stator chute is greatly restricted.

Abstract

The invention discloses a stator with a low-harmonic winding, a driving motor and a vehicle. The stator comprises an iron core and a plurality of conductive parts, wherein a plurality of stator slots which are uniformly distributed around the axial direction of the iron core are formed in the inner wall of the iron core, the slot directions of the plurality of stator slots are parallel to the axial direction of the iron core, the opening directions of the plurality of stator slots face the axis of the iron core, each stator slot is sequentially provided with a first accommodating position and a second accommodating position in the radial direction of the iron core, one end of each conductive part is connected to the first accommodating position or the second accommodating position of one stator slot, the other end of each conductive part is connected to the first accommodating position or the second accommodating position of the other stator slot at a preset interval in the circumferential direction of the iron core, the conductive part connected with the first accommodating position and the second accommodating position in the same stator slot is used for introducing alternating current of different phases, and the plurality of conductive parts are square conductors. The stator is used for weakening harmonic waves and improving the motor performance, and can achieve the effect equivalent to a stator chute under the condition that the conductive parts are square conductors.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a stator with low harmonic windings, a driving motor and a vehicle. Background technique [0002] In the related technology, by opening a stator chute on the stator core and using a winding made of square conductors, the sinusoidality of the induced potential waveform can be changed, harmonics can be reduced, and the performance of the motor can be improved. However, due to the high hardness of the square conductor, it is difficult to twist, and the insulating varnish on its surface will be damaged when it is bent and twisted, and the insulation of the winding will be damaged, so the application of the square conductor in the stator chute is greatly restricted. Contents of the invention [0003] Embodiments of the present invention provide a stator, a drive motor and a vehicle with low harmonic windings. [0004] A stator with low harmonic windings provided in an embodiment of ...
