Abstract

The invention discloses a chain type stator core and a motor, which are used for solving the problem that when a lamination coefficient of a stator core is relatively large, the space between stator core laminations of each layer is too small, so that the rotation is difficult. The chain type stator core comprises a plurality of stator core units, wherein an arbitrary stator core unit is formed by laminating a plurality of stator core laminations, the stator core laminations of two adjacent stator core units are mutually rotated and buckled together to form a stator core chain, the two ends of the stator core chain are fixedly connected to form the chain type stator core, and the distance between the rotating connection overlapping areas of the two stator core laminations which are mutually and rotatably buckled is larger than the distance between the non-rotating connection overlapping areas of the two stator core laminations which are mutually and rotatably buckled. According to the chain type stator core, the thickness of the rotating connection overlapping areas of the stator core laminations is smaller than that of the non-rotating connection overlapping areas, so that the problem that two adjacent stator core units cannot rotate relatively due to overlarge extrusion force is solved; and meanwhile, the lamination coefficient of the stator iron core is further increased.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a chain-type stator core and a motor. Background technique [0002] like figure 1 As shown in the figure, the chain-type motor rotates hingedly through the convex joint 1 and the concave joint 2 between the stator core units, so that the space for inserting wires at the stator teeth becomes larger. Compared with the conventional motor with an integral stator core, it can greatly Improve the slot full rate of the motor, thereby improving the efficiency of the motor. However, due to the rotation of the convex joint 1 and the concave joint 2, the lamination coefficient of the axially laminated stator core is limited. If the distance between them is too small, it will be difficult to rotate. Contents of the invention [0003] In view of this, the present invention discloses a chain-type stator core and a motor, which are used to solve the problem of difficult rotation caused by t...
