Problems solved by technology

[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 winding, resulting in an increase in cost

Abstract

Disclosed is a stator and a motor thereof. The stator comprise a yoke portion which is overlain by multiple punching plates of the yoke portion, a main gear portion which is overlain by multiple punching plates of the gear portion and is installed on the yoke portion and the punching plate of the gear portion is vertically set up with punching plates of the yoke portion, and a gear boot portion which is overlain by multiple punching plates of the gear boot portion and is installed on the main gear portion and the punching plate of the gear boot portion is vertically set up with punching plates of the gear portion and a yielding hole for revealing the main gear portion is equipped on the inside surface radially of the yoke portion, as well as a winding which is twined around the main gear portion. The axial size of the parts of the stator can be set up independently, which is beneficial to adjust the performance of the motor and get a cost low.

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...
