The invention discloses a flat wire motor stator and a flat wire motor. The stator includes a stator core and a stator winding; each phase of the stator winding includes N parallel branches; the star point connection ends of each parallel branch are drawn from different winding slots on the connection side, and the three-phase windings are connected to the first and Each star-point connecting end connected by the second star-point connecting line is drawn out from the adjacent winding slot on the connection side; each power lead-out end of the same phase winding is drawn out from the same and / or adjacent winding slot on the connecting side and is drawn out through the power supply Wire connection; in this way, the centralized distribution of each star-point connection end and each power lead-out end simplifies the winding structure of the connection side end and reduces the difficulty of winding coil welding production; in addition, the point of electrical connection with the first and second star-point connection lines is drawn out The winding slots at the connection end are symmetrically distributed on opposite sides of the winding slots leading out from the power supply outlet, and the winding slots leading out from each star point connection end are adjacent to the winding slots leading out from the power supply outlet, which is beneficial to reduce the distance between each branch. circulating current between them.
Description
technical field [0001] The embodiments of the present invention relate to motor technology, and in particular to a flat wire motor stator and a flat wire motor. Background technique [0002] With the rapid development of new energy vehicle technology, the performance requirements for vehicle drive motors are getting higher and higher. The increase in performance will inevitably lead to an increase in the volume of the drive motor. However, the axial space size of new energy vehicles is very limited, resulting in the drive motor. The contradiction between performance and volume is becoming increasingly prominent. [0003] At present, the driving motors of new energy vehicles are mainly permanent magnet synchronous motors. In permanent magnet synchronous motors, the motor stator can be divided into round wires and flat copper wires according to the cross-sectional shape of the stator winding. Motors using flat copper wires are called Flat wire motor. At present, most permane...
