Low-noise high-vibration totally enclosed micro motor

Abstract

The invention discloses a low-noise high-vibration totally enclosed micro motor comprising a shell. The stator component, the rotor component and the end cap component of the motor are arranged in the enclosed shell. The connecting terminals of the end cap component are exposed out of the barrel-shaped shell. A bearing support and an oil pad are additionally arranged in the direction of an oscillator so that the noise level of the motor can be substantially reduced and the production efficiency can be enhanced; and the bearing support is closely combined with the shell through four bosses arranged at the periphery so that the bearing support is enabled not to be separated. The content of lubricating oil can be saved by the oil pad so that noise can be effectively reduced.

Description

technical field [0001] The invention relates to the field of motors, in particular to a fully enclosed micro motor with low noise and high vibration. Background technique [0002] Micro vibration motors are mainly used in electronic products such as mobile phones, Smart-watches, Bluetooth devices, PADs, Notebooks, etc., to function as silent vibration reminders. The structure of the traditional SMD motor is generally that the vibrator is exposed, and the shell and the bracket are combined to fix the motor. During the motor assembly and testing process, the motor shaft failure after bending and the motor noise have always been troublesome problems for manufacturers and customers. [0003] In response to this problem, the applicant proposed a micro-motor and its support with application number 2015104651877, which encloses the main body of the motor by using a cuboid barrel-shaped shell. In this plan, only the feasibility of the technology is considered, and no detailed plan ...

AI Technical Summary

Problems solved by technology

In this plan, only the feasibility of the technology is considered, and no detailed plan is proposed for the specific implementation of the technology, and the plan can only be regarded as semi-closed, and the two ends of the shell are open. During use, because the open The type of shell makes the motor still vibrate violently and make a lot of noise, so it is not suitable for large-scale use

Especially because of the open structure, during the soldering process, there is a high probability that the solder will enter the casing and affect the main body of the motor. Therefore, the semi-closed structure is not suitable for mass production, and it cannot greatly improve the quality of the motor. the role of
