Motors and electronic equipment with motors

Abstract

The present invention relates to the field of motor technology, and provides a motor and electronic equipment with the motor. The motor includes: a casing, a stator and a rotor arranged in the casing; the stator includes: a stator core, a coil, a circuit board and A bearing cage; the bearing cage is fixed on the casing; the rotor includes: a shaft, a rotor frame and a rotor magnet; the bearing cage has a disc-shaped base, and two A first cylindrical part and a second cylindrical part extending sideways; the first cylindrical part accommodates a first bearing; the outer periphery of the second cylindrical part is fixed with a stator core; the second cylindrical part The end is aligned with or protrudes from the axial end of the stator core. The invention can ensure that most of the iron core is in contact with the matching part of the iron core of the bearing cavity part, thereby ensuring higher matching strength and flatness of the iron core after being pressed in; at the same time, the glue coating process is reduced, and the number of man-hours and the cost of production 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 and so on. [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,...

AI Technical Summary

Problems solved by technology

[0004] The present invention mainly solves technical problems such as lack of flatness of the motor iron core in the prior art, adding glue between the iron core and the bearing cavity for fixing, which consumes a lot of manpower and other technical problems, and proposes a motor and electronic equipment with the motor to ensure that most of the iron core Both are in contact with the matching part of the iron core of the bearing cavity to ensure higher fit strength and flatness of the iron core after pressing in; at the same time, reduce the glue coating process, reduce the number of man-hours and costs of production
