Problems solved by technology

However, in this way, the assembly operation between the multiple modules of the stator yoke is relatively difficult, and usually needs to be completed with the help of other tools, thus limiting the production efficiency of the motor stator
In addition, when the motor stator is installed on the motor casing, the segmented stator core is prone to axial misalignment and other problems

Abstract

The invention discloses a motor stator and a motor having the same. The motor stator includes a stator core and a stator winding. The stator core includes a plurality of sub-stator cores, and each sub-stator core includes a stator yoke, at least one stator tooth and Two connecting outer ends, the two connecting outer ends are arranged on the outer side of the stator yoke and are respectively located at both ends of the stator yoke in the circumferential direction, the stator teeth are arranged on the inner side of the stator yoke and on the circumference of the stator yoke It is upwardly located between the two connecting outer ends, and each connecting outer end is formed with a groove, and the two grooves of the two connecting outer ends that are in contact with the adjacent two stator cores form a mounting hole. Connectors are fitted in the holes to realize the connection and installation positioning of two adjacent stator cores, and the stator windings are wound on the stator teeth. According to the motor stator of the present invention, the manufacture is convenient, the assembly difficulty is small, and the production efficiency is high, and at the same time, it is easy to ensure the axial positioning between the adjacent stator cores.

Description

technical field [0001] The invention relates to the technical field of motor manufacturing, in particular to a motor stator and a motor having the same. Background technique [0002] In the related art, most of the stator cores of the motor adopt an integrated structure, which makes it inconvenient to wind the wire on the stator yoke, which leads to inconvenient and low processing efficiency of the motor stator. In order to simplify the production process of the motor stator, in some technologies, during the production of the motor stator, the stator yoke, the stator teeth and the stator winding are respectively modularized, and then these modules are assembled into a complete motor stator. However, in this way, the assembly operation between the multiple modules of the stator yoke is relatively difficult, and usually needs to be completed with other tools, thereby limiting the production efficiency of the motor stator. In addition, when the motor stator is installed on the...
