[0005] However, the above-mentioned S-shaped waveform coil, such as figure 1 As shown, when winding, the pitches of the effective sides of the S-shaped wavy lines of each line in each phase line are equal, and the effective sides of the S-shaped wavy lines of each line in each phase line are placed in sequence In the stator slot body, for the above-mentioned motor stator, the number of slots distributed per pole and phase is equal to the number of controllers to be controlled. For example, three slots are distributed per pole and each phase. For silicon rectified alternators, three rectifier bridges are required to control , for the motor, three controllers are needed for control, if four slots are distributed for each pole and each phase, for the silicon rectifier alternator, four rectifier bridges are needed for control, for the motor, four controllers are needed for control, so the motor circuit design Complex, expensive to manufacture, prone to failure

Abstract

The invention discloses a flat wire continuous wave staggered winding and a stator comprising the same and belongs to the technical field of motor manufacture. The flat wire continuous wave staggeredwinding is composed of a wire inlet end lead part (101), a wire outlet end lead part (102) and an S-shaped S wave line (103). The S-shaped wave line (103) includes an active side part (301), a straight line part (302) and an end part (303). The S-shaped wave line (103) is provided with a staggered winding part (304) in which the leads of different phases are arranged in a staggered manner. According to the invention, single three-phase control can be realized for motors or generators with different slot number of each phase and each electrode. Therefore, a motor circuit can be simplified and manufacture cost can be reduced. Secondary harmonics of the motor can be reduced, motor noise can be reduced and product quality can be improved.

Description

technical field [0001] The invention relates to the technical field of motor manufacturing, in particular to an AC motor, including a motor and a generator, and in particular to a continuous-wave flat-wire wound dislocation winding and a stator containing a flat-wire continuous-wave wound dislocation winding. Background technique [0002] For rotating electrical machines, in order to enhance the performance of rotating electrical machines, it is necessary to increase the space factor of the stator in the slot and increase the slot fullness rate. Therefore, it is a feasible way to use flat wires with rectangular cross-sections as materials for forming stator windings. It is also a better method. [0003] On March 26, 1998, the Chinese invention patent with the application number 981078494 discloses an alternator for automobiles, the multi-phase stator winding includes a plurality of electrical conductors, and the plurality of electrical conductors constitute at least one pair...
