Motor shell electrostatic protection device

Abstract

The invention provides a motor shell electrostatic protection device, relates to the technical field of electrostatic protection devices, solves the problem that rapid contact between charges on an elimination head and charges on a motor shell cannot be realized through structural improvement, and solves the problem that dust on the head cannot be automatically cleaned through structural improvement cannot be solved. The motor shell electrostatic protection device comprises a base, wherein an eliminating structure is mounted on the base; and the number of eliminating heads is two, and the twoeliminating heads are symmetrically installed on the rear end face of the main body base. Six through holes are formed in each eliminating head on the main body base in an annular array shape, the through holes formed in the annular array shape jointly form a wind power blowing-away structure for eliminating charges on the eliminating heads, and the through holes are of a conical hole structure, so that the charges generated on the eliminating heads can be blown away to a driving motor through wind power jet flow at the through holes, and the through holes of the conical hole-shaped structuresare beneficial to enhancing the wind power gathering effect.

Description

technical field [0001] The invention belongs to the technical field of electrostatic protection devices, and more specifically relates to an electrostatic protection device for motor casings. Background technique [0002] The motor shell is generally produced by casting process, and then after many times of mechanical processing to the finished product, it provides a protection device for the motor to ensure the safety of the motor. Static electricity is a static charge or a non-flowing charge. In a dry environment, static electricity is easy to accumulate on the motor casing, which not only easily causes damage to the electrical components in the motor, but also affects the use of the motor. [0003] For example, the application number: CN202020550966.3 discloses a motor housing electrostatic protection device, which includes a motor housing, an insulating plate and a patch. An isolation cavity is formed between the motor casings, the patch is bonded to the inner side wall...

AI Technical Summary

Problems solved by technology

[0007] In order to solve the above technical problems, the present invention provides a motor casing electrostatic protection device to solve the problem that the existing device has low efficiency in eliminating static electricity on the motor casing and cannot be eliminated through structural improvement. The charge on the head contacts the charge on the motor casing quickly, which leads to the neutralization efficiency of the two charges; moreover, the elimination head of the existing device is easy to accumulate dust and affects the elimination efficiency, and cannot be improved through structural improvement Realize the problem of automatic cleaning cleaning that eliminates dust on the head
