Abstract

本发明涉及一种交流变极三速三相感应电机,在其定子放置两套三相绕组,一套三相定子绕组具有高速极对数p1和中速极对数p2,其中对于高速极对数p1为两路星形并联(2Y)接法,对于中速极对数p2为三角形(Δ)接法,有六个引出线端;另一套三相定子绕组具有中速极对数p2和低速极对数p3,其中对于中速极对数p2为三角形(Δ)接法,对于低速极对数p3为两路星形并联(2Y)接法,也有六个引出线端;这两套三相定子绕组对于中速极对数p2均为三角形(Δ)接法,并将之并联连接,最后形成的整个三相定子绕组的引出线端共有9个。本发明的绕组导体利用率高,温升低,损耗减小,变极控制简便。
The invention relates to an alternating-current pole-changing three-speed three-phase induction motor. Two sets of three-phase windings are arranged on a stator of the induction motor; one set of three-phase stator winding has high-speed pole pairs p1 and medium-speed pole pairs p2, wherein for the high-speed pole pairs p1, the windings are in two-path star parallel connection (2Y), and for the medium-speed pole pairs p2, the windings are in triangular connection (triangle), and have 6 leading-out wire ends; the other set of three-phase stator winding has the medium-speed pole pairs p2 and low-speed pole pairs p3, wherein for the medium-speed pole pairs p2, the windings are in the triangular connection (triangle), and for the low-speed pole pairs p3, the windings are the two-path star parallel connection (2Y) and have 6 leading-out wire ends; and for the medium-speed pole pairs p2, the two sets of three-phase stator windings are in the triangular connection (triangle) and are connected in parallel, and the formed leading-out wire ends of the integral three-phase stator windings are nine. The alternating-current pole-changing three-speed three-phase induction motor has the high utilization rate and low temperature rise of winding conductors, reduces the loss, and is simple and convenient for pole-changing control.
