Abstract

The invention discloses a method for motor maintenance, which includes: (1) preparatory work: including placing hoisting equipment in place and making a rotating support, wherein the hoisting equipment includes a crane, a pole beam and a chain block; (2) assisting Equipment removal: Remove the motor rotor coupling guard, coupling bolts, cooler, fan cover and fan, upper bearing bush, anchor bolts, motor power connector, motor winding, bearing bush temperature measurement probe; (3) The motor rotor is extracted from the inside of the motor stator; (4) the motor rotor extracted from the motor is placed on the rotating support and the motor rotor is overhauled. The motor maintenance method provided by the present invention mainly eliminates the problem of displacement between the motor rotor lining board and the motor rotor core by welding the motor rotor lining board and the motor rotor iron core.

Description

Technical field: [0001] The invention relates to the professional field of electromechanics, in particular to a method for motor maintenance. Background technique: [0002] At present, when the high-power high-voltage motors of domestic industrial and mining enterprises fail, they all return to professional maintenance manufacturers for overhaul. Returning to a professional maintenance factory for maintenance will cause the equipment to be out of service, which is time-consuming and labor-intensive, and will cause great economic losses to the company. [0003] The continuous production process of our company puts forward higher requirements for the reliable and stable operation of the equipment, especially if the factory control and key equipment in operation fail, it may cause the shutdown of the equipment, which will bring huge losses to the company's production Economic losses. Invention content: [0004] The purpose of the present invention is to provide a method for...
