Stator and motor with same

Abstract

The invention discloses a stator and a motor with the same. The stator comprise a yoke part, a main gear part, a first gear boot part, a second gear boot part and a winding, wherein the yoke part is formed by laminating a plurality of yoke part punching sheets, the main gear part is formed by laminating a plurality of gear part punching sheets and is arranged on the yoke part in a clamping way, the gear part punching sheets are arranged in perpendicular to the yoke part punching sheets, an extending part is arranged at one end, facing an inner side in a radial direction of the yoke part, of the main gear part and extends along an axial direction of the yoke part, two ends of the extending part protrude out of the main gear part, the first gear boot part is formed by laminating a plurality of first gear boot punching sheets and is arranged at one end of the extending part in a clamping way, the first gear boot punching sheets are arranged in perpendicular to the gear part punching sheets, the second gear boot part is formed by laminating a plurality of second gear boot punching sheets and is arranged at the other end of the extending part in a clamping way, the second gear boot punching sheets are arranged in perpendicular to the gear part punching sheets, and the winding is wound around the main gear part. According to the stator disclosed by the embodiment of the invention, the axial size of each part can be independently set, so that the motor performance is favorably adjusted, and the stator is relatively low in cost.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a stator 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 material consumption of the iron core and...
