Description

Technical Field

[0001] The utility model relates to the technical field of motors, in particular to a high-efficiency magnetic circuit motor which can effectively reduce noise. Background Art

[0002] An electric motor, commonly known as a motor, is an electromagnetic device that converts or transmits electrical energy based on the law of electromagnetic induction. Its main function is to generate driving torque as a power source for electrical appliances or various machines.

[0003] Generally, electric motors will generate a lot of noise during operation. The common reason why electric motors generate excessive noise during operation is that after the motor has been used for a period of time, the rotating connection between the motor output shaft and the housing will wear out, causing a large relative displacement between the housing and the shaft, increasing the contact friction and the vibration amplitude of the motor, thereby generating a lot of noise. Currently, there are many motor sound insulation covers on the market that isolate noise through sound insulation panels, but ultimately they cannot reduce the noise at the source.

[0004] To this end, we propose a high-efficiency magnetic circuit motor that effectively reduces noise. Utility Model Content

[0011] Optionally, a fan is fixedly mounted at the end of the rotating shaft and is located between the fan cover and the rear end cover.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The high-efficiency magnetic circuit motor which effectively reduces noise is provided with a plurality of positioning components. When the rotating shaft rotates, the pushing rod is pushed to extend outward by the pressing spring, thereby pushing the swing rod to deflect, so that the roller is pressed against the rotating shaft, and the plurality of rollers are pushed at the same time, so that the axis of the rotating shaft is always kept coincident with the axis of the outer shell and the front end cover, thereby reducing the wear of the rotating shaft and each rotating connection, and at the same time reducing the vibration of the rotating shaft and reducing the generation of noise.

The other end of the telescopic cover 84 is rotatably connected to the front end cover 2. By setting a plurality of positioning components 8, when the rotating shaft 5 rotates, the clamping spring 85 pushes the push rod 83 to extend outward, thereby pushing the swing rod 81 to deflect, so that the roller 82 is pressed against the rotating shaft 5. Multiple rollers 82 are pushed at the same time, so that the axis of the rotating shaft 5 always coincides with the axis of the outer shell 1 and the front end cover 2, thereby reducing the wear of the rotating shaft 5 and the rotating joints, and at the same time reducing the vibration of the rotating shaft 5 and reducing the noise generation.

By setting a positioning component 8, when the rotating shaft 5 and each rotating connection are worn, the rotating shaft 5 is pushed by multiple rollers 82, so that the axis of the rotating shaft 5 always coincides with the axis of the outer shell 1 and the front end cover 2, thereby preventing the rotating shaft 5 from shaking and further reducing noise.

[0025] A bearing 9 is fixedly installed at the rotation connection between the rotating shaft 5 and the front end cover 2, and the middle parts of the rotating shaft 5 and the bearing 9 are penetrated and fixedly installed.

[0026] Working principle:

When the shaft 5 and the rotating joints are worn, the shaft 5 is pushed by multiple rollers 82, so that the axis of the shaft 5 is always kept coincident with the axis of the shell 1 and the front end cover 2, thereby preventing the shaft 5 from shaking and further reducing the noise.
