Motor and electronic equipment with same

Abstract

The invention relates to the technical field of motors, and provides a motor and electronic equipment with the motor, and the motor comprises a housing, and a stator and a rotor which are disposed inthe housing. The stator comprises a stator core, a coil, a circuit board and a bearing retainer. The bearing retainer is fixed on the shell; the rotor comprises a shaft, a rotor frame and a rotor magnet. The bearing retainer is provided with a disc-shaped base part, a first cylindrical part and a second cylindrical part, wherein the first cylindrical part and the second cylindrical part extend from the center of the base part along the two sides in the axial direction. A first bearing is accommodated in the first cylindrical part; a stator iron core is fixed at the periphery of the second cylindrical part; and the end part of the second cylindrical part is aligned with the axial end surface of the stator iron core or protrudes out of the axial end part of the stator iron core. According tothe invention, most of the iron core can be ensured to contact with the matching part of the iron core of the bearing cavity part, and higher matching strength and flatness after the iron core is pressed in are ensured; and meanwhile, the gluing process is reduced, and the number of production processes and cost are reduced.

Description

technical field

[0001] The invention relates to the technical field of motors, in particular to a motor and electronic equipment with the motor. Background technique

[0002] Motors are widely used in various electronic devices in daily work and life, such as refrigerators, washing machines, fans, air conditioners, clocks, etc.

[0003] In the existing motor structure, the plane of the front side of the iron core is higher than the plane of the fixed part of the iron core in the bearing cavity; glue is added between the iron core and the bearing cavity to fix it; in this case, the flatness of the iron core will be insufficient. The copper wire produces an irregular magnetic field, which produces certain vibration and noise. Moreover, the gluing process also consumes more man-hours, which increases the production cost. In addition, during the riveting process of the casing and the bearing cage, when the riveting part of the casing is bent, they contact at right angles, whic...
