Abstract

The invention provides a motor stator and a motor using the same. The motor stator comprises a stator iron core which is provided with a stator slot, the stator slot comprises a plurality of slot layers, and the slot layers are arranged along the radial direction of the stator iron core; the stator winding is inserted into the stator slots, the stator winding comprises a plurality of first conductors and a plurality of second conductors, and each of the first conductors and the second conductors comprises two linear segment parts; wherein the linear segment parts of the plurality of first conductors are respectively located in two adjacent slot layers, each of the first conductors and the second conductor comprises two linear segment parts, and one linear segment part of the second conductor and one linear segment part of the first conductor are located in the same stator slot; the polar distance of the stator winding is tau, the pitch of the second conductors is y2, the distance between the linear segment parts of the two adjacent first conductors in the same slot layer is L1, and the distance between the linear end parts of the adjacent second conductors is L2. The height of the bending part of the stator coil can be reduced, and the motor efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a motor stator and an applied motor. Background technique [0002] The stator core winding adopts the method of flat wire (rectangular wire), which can greatly improve the full ratio of bare copper slots of the stator coil, thereby greatly improving the efficiency of the motor. The stator winding includes a plurality of hairpin coils, and the plurality of hairpin coils are inserted into the stator slots of the stator iron core according to a certain arrangement to form the required windings of a single-phase motor or a multi-phase motor. [0003] However, there are many types of existing stator hairpin coils, and the arrangement is complicated. In the same stator slot, the voltage difference between the layers of different slot layers is high. When used under high voltage, the hairpin coils between different slot layers are easy to use. The phenomenon of breakdown occurs, resulti...
