Zusammenfassung: | The utility model discloses a stator for an elevator tractor. The stator comprises windings and an iron core, wherein the iron core comprises a fastening bolt (2), a bushing (3) and a plurality of sectorial stator teeth (1) which are closely arranged along the circumferential direction; and each stator tooth (1) is wound with an independent winding (4) and is fixedly fastened on the bushing (3) through the fastening bolt (2). Due to the structure, the whole stator is formed by combining a plurality of stator units, the length of the end part of an armature winding is greatly shortened, and the thickness of a motor body is reduced, so that the stator for the elevator tractor can adapt to the arrangement of machine roomless and small machine room elevators and reduces the material cost at the same time. |
