Abstract

The invention belongs to the field of motors, and discloses a stator iron core, a stator and a motor. The stator iron core comprises at least three split bodies, and each split body comprises a sub-yoke and at least one stator tooth, wherein each sub-yoke is closed in the circumferential direction, the thickness of each sub-yoke is smaller than that of the stator iron core, the stator teeth are arranged on the sub-yokes, and the thickness of the stator teeth is equal to that of the stator iron core. The sum of the thicknesses of the sub-yokes is equal to the thickness of the stator iron core, the split bodies are axially stacked to form the stator iron core in the mode that the stator teeth are staggered mutually, and the two adjacent sides of one stator tooth of each split body are the two stator teeth on another two split bodies. Due to the facts that firstly, independent winding is performed on each split body, and then the split bodies where winding is completed are axially stacked to form the overall stator, the winding efficiency of the stator is improved, the slot fullness rate of the stator is increased, the performance of the motor is improved, the roundness precision of the stator is guaranteed, and the assembling process is simplified.

Description

technical field [0001] The invention belongs to the field of motors, in particular to a stator core, a stator with the stator core, and a motor with the stator. Background technique [0002] A traditional manufacturing method of the motor stator is as follows: First, the stator punches are punched out as a whole, and then the stator punches are laminated to form an integral stator core, and then the stator winding is wound on the integral stator core by a winding machine . The traditional manufacturing method of the stator has the following defects in specific applications: due to the limitation of the winding space requirements, the slot fill rate is not high, and the opening of the slot on the stator core needs to be designed larger, which affects the Improved motor performance. [0003] In order to solve the above-mentioned technical problems in the traditional stator manufacturing method, the prior art proposes two schemes for winding the stator core separately: [00...
