The invention relates to a stator assembly, a permanent magnet synchronous motor and an elevator traction machine, a stator core comprises an annular yoke part, a plurality of outer teeth arranged along the outer periphery of the annular yoke part at intervals and a plurality of inner teeth arranged along the inner periphery of the annular yoke part at intervals, and every two adjacent outer teeth are spaced to form a first spacing groove; every two adjacent inner teeth are spaced to form a second spacing groove, and one first spacing groove and one second spacing groove are correspondingly arranged in the radial direction of the annular yoke part; the number of the stator teeth is multiple, the two sides of each inner tooth are each correspondingly provided with one stator tooth in the axial direction of the annular yoke part, and every two adjacent stator teeth are spaced in the circumferential direction of the annular yoke part to form a third interval groove communicated with the corresponding second interval groove. And one first interval groove, one second interval groove and one third interval groove which correspond to each other are matched to form a winding groove. And the stator core and the stator teeth are combined, so that the stator assembly is simpler to process and manufacture, and the manufacturing cost is reduced.
本发明涉及一种定子组件、永磁同步电机及电梯曳引机,其中,定子铁芯包括环形轭部、沿环形轭部的外周间隔设置的多个外齿及沿环形轭部的内周间隔设置的多个内齿,相邻的两个外齿间隔形成第一间隔槽,相邻的两个内齿间隔形成第二间隔槽,且一个第一间隔槽与一个第二间隔槽沿环形轭部的径向方向对应设置;定子齿为多个,沿环形轭部的轴向,每个内齿的两侧均对应设置一个定子齿,沿环形轭部的圆周方向,相邻的两个定子齿间隔形成与对应的第二间隔槽连通的第三间隔槽,且相互对应的一个第一间隔槽、一个第二间隔槽及一个第三间隔槽配合形成一个绕线槽。结合定子铁芯与定子齿的组合,使得定子组件的加工制造更加简单,降低了制造成本。
