Motor with segmented stators

Abstract

The invention discloses a motor with segmented stators. The motor comprises a housing and a plurality of segmented stator iron cores, wherein both ends of a yoke part of each segmented stator iron core are provided with a convex connecting part and a concave connecting part respectively; the convex connecting parts and the concave connecting parts of every two adjacent segmented stator iron cores are embedded with each other and connected into a circular stator iron core; the motor also comprises a plurality of axial locating key slots which are arranged along the peripheral direction of the housing; and the segmented stator iron cores are connected with the axial locating key slots of the housing by axial locating keys. In the motor with the segmented stators, provided by the invention, the segmented stator iron cores are connected with the axial locating key slots of the housing by the axial locating keys, and the segmented stator iron cores are reliably arranged in the axial direction of the housing, so that the segmented stator iron cores are unlikely to misplace in the axial direction to fall, the connection among the segmented stator iron cores is kept tight, and the connection strength among the segmented stator iron cores is improved.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a motor with segmented stators. Background technique [0002] Motor refers to an electromagnetic device that converts or transmits electric energy according to the law of electromagnetic induction. Motors are widely used in industrial and agricultural production, transportation, national defense, commercial and household appliances, and medical electrical equipment. [0003] The iron core of the traditional motor stator is mostly laminated with a whole piece of electrical steel. Due to the method of full-circle punching, the utilization rate of silicon steel material is very low; The end of the stator winding is long, but the end winding cannot generate effective electromagnetic torque, and the waste of copper wire is serious; in addition, for the convenience of embedding wires, the slots of the stator are relatively large, and the slot fullness of the motor is low, which affects ...
