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 with the motor stator. The motor stator comprises a stator core and a stator winding, wherein the stator core comprises a plurality of sub stator cores; each sub stator core comprises a stator yoke part, two sub stator tooth parts and two connecting outer end parts; the stator winding is wound on the stator yoke parts; the two sub stator tooth parts are arranged on the inner side of the corresponding stator yoke part respectively and are positioned at two ends of the corresponding stator yoke part in the peripheral direction respectively; thetwo connecting outer end parts are arranged on the outer side of the corresponding stator yoke part respectively and are opposite to the two corresponding sub stator tooth parts respectively; a grooveis formed in each connecting outer end part; two grooves of the connecting outer end parts in contact with the two adjacent sub stator cores form a mounting hole; and each mounting groove is internally matched with a connecting piece so as to realize connection and mounting positioning of every two adjacent sub stator cores. According to the motor stator disclosed by the invention, the motor stator is convenient to manufacture, small in assembling difficulty and high in production efficiency, and axial positioning between every two adjacent sub stator cores is easily guaranteed.

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...
