A kind of anti-corrosion maintenance method of stepper motor

Abstract

The invention belongs to the technical field of motors and particularly discloses an anti-corrosion maintenance method for a stepping motor. A spiral plate is arranged in a non-power output directionof a rotor through a connection pipe; the other end of the connection pipe is connected onto one end of the rotor in a matched mode and is in rotating connection with a shell through a sleeve; the spiral plate is internally provided with a group of alternately-arranged vertical plates; and the power output direction of an output shaft is provided with a brush cleaning module, the brush cleaning module is in power connection with the output shaft, and the brush cleaning module scrapes condensed water on the outer wall of the shell. The condensed water on the surface of the motor can be timely discharged, corrosion of the shell is prevented, the risk that water enters the inner part of the motor caused by not tightly sealing of the motor can be avoided, and the service life of the motor is improved.

Description

technical field [0001] The invention belongs to the technical field of electric motors, in particular to an anti-corrosion maintenance method for a stepping motor. Background technique [0002] In the air-conditioning structure, the air-conditioning deflector is in the main area of ​​heat exchange, and often produces more condensed water. The stepper motors used for transmission are generally directly exposed and fixed on the components in the air conditioner. There is no waterproof device on the surface of the motor, and the output shaft of the motor is only sealed with grease, and the air conditioner often produces condensed water when it is working. The condensed water is easy to drip on the motor and cause damage to the motor, which can easily affect the normal operation of the stepper motor and even cause some safety hazards.

AI Technical Summary

Problems solved by technology

The stepper motors used for transmission are generally directly exposed and fixed on the components in the air conditioner. There is no waterproof device on the surface of the motor, and the output shaft of the motor is only sealed with grease, and the air conditioner often produces condensed water when it is working. The condensed water is easy to drip on the motor and cause damage to the motor, it is easy to affect the normal operation of the stepper motor, and even cause some safety hazards

[0003] Some existing technical solutions are to further improve the sealing of the stepping motor to realize the waterproofing of the stepping motor; it does not effectively discharge the condensed water, so that the sealing material is soaked in water for a long time, and the sealing performance will decrease over time. As the rate of failure gradually decreases, the incidence of failure also gradually increases; and the screws used to fix the motor are soaked in water for a long time, which is prone to rust, which makes the repair and maintenance of the air conditioner very unfavorable.
