Abstract

The invention discloses a stator core, a stator and a motor. The stator core is arranged at the periphery of a rotor. The stator core comprises multiple single stators which are arranged at intervals along the circumference of the rotor. Each single stator comprises a yoke, two main teeth, and a tooth shoe, wherein the yoke is composed of multiple yoke punching sheets extending along the circumference of the rotor which are laminated along the axial direction of the rotor, the two main teeth are clamped to the two circumferential ends of the yoke respectively, each main tooth is formed by laminating multiple tooth punching sheets which are perpendicular to the yoke punching sheets and extend along the radial direction of the yoke, the inner end of each main tooth is provided with an extension which extends along the axial direction of the yoke and has at least one end protruding from the main tooth, the tooth shoe is formed by laminating multiple tooth shoe punching sheets, the tooth shoe is provided with an open slot which is opened in a direction parallel to the laminating direction of the tooth punching sheets, and the extensions are clamped into the open slot. The stator core disclosed by the embodiment of the invention is of higher magnetic flux gathering ability and lower cost.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a stator core, a stator with the stator core and a motor with the stator. Background technique [0002] In the motor in the related art, the stator yoke, teeth and tooth shoe are punched out as one piece, so the dimensions of the yoke, tooth and tooth shoe in the axial direction of the stator are consistent. For a unit surface area For a rotor with a weak magnetic field or a low rotation frequency, in order to save stator materials and improve its performance, the size of the yoke and teeth needs to be thinner and the area of ​​the tooth shoe larger, but affected by the radius of the inner circle of the stator, through Increasing the width of the tooth shoe to increase the area of ​​the tooth shoe has limited effect, and if the tooth shoe is expanded in the axial direction of the stator, the axial dimension of the yoke and the teeth will be lengthened, thereby increasing the mater...
