The invention provides a stator structure and an iron core yoke part. The iron core yoke part comprises a substrate, a first surface, a second surface, a first combination part and a second combination part. The first surface is located on one side of the substrate and comprises a first inclined surface and a second inclined surface. The second surface is located on the other side of the substrate and comprises a third inclined surface and a fourth inclined surface. A first groove is formed between the first inclined surface and the third inclined surface. A second groove is formed between the third inclined surface and the fourth inclined surface, wherein the an angle between the first inclined surface and the third inclined surface is smaller than 180 DEG, and an angle between the third inclined surface and the fourth inclined surface is smaller than 180 DEG. In addition, the invention also provides a stator structure.
Description
technical field [0001] The invention relates to a motor structure, in particular to a stator structure and its iron core yoke. Background technique [0002] Traditional motors use silicon steel sheets as the magnetic core, which is formed by stamping and stacking individual silicon steel sheets. Taking motors as an example, whether they are brushed motors or brushless motors, most of them adopt a radial flux structure. Radial flux motors are divided into outer-rotating and inner-rotating motors according to the position of the rotor. Due to the presence of magnets and a large amount of magnetically conductive materials in the motor, the design of the motor magnetic circuit is limited by the structure of the silicon steel sheet, and it is impossible to achieve a three-dimensional magnetic circuit structure to reduce magnetic flux leakage, resulting in a limited torque density of the motor. [0003] Looking at the traditional motor, because it uses silicon steel sheet as the ...
