Dongguan YanHua numerical control mechanical and electrical co., LTD. Is a main shaft, servo motor, circuit board maintenance maintenance of professional maintenance company.
   Servo motor repair service industry is an emerging technology.In recent years, the servo motor is more and more widely used, the usage of mainland China market proliferated, servo motor repair this technical service demand is becoming more and more urgent.Due to domestic use of servo motor is mostly imported products, high technology content, servo motor manufacturers in order to monopolize the maintenance services market abroad, adopted the non-standard encoder or non standard installation, make servo motor maintenance becomes difficult, formed the servo motor maintenance is an outstanding technical ability.
   Servo motor repair is divided into mechanical parts and electrical maintenance maintenance.
   Part 1, mechanical repair for bearing damage replacement.Compared with the conventional motor repair, just special bearing.Because most of the servo motor is a synchronous motor, rotor with magnetic poles, using ordinary materials will not be able to solve the problem, so the key to material custom especially, at the same time registration request also is higher than general motors, but the change process is not complicated, and the maintenance of general motor difference is not big.
   Part 2, mainly for the winding of electric parts maintenance and repair of the magnetization and encoder.
   (1) winding, choose copper wire to the high quality material.
Magnetization needs to have a certain technical content,

   (2) is usually the magnetization, the magnetization and closed to open the magnetization; the former is suitable for some of the stator magnetic fieldMagnetization requires skill, and open it in addition to the need to learn that the magnetic intensity of the original motor, also need to understand the distribution of shape to guaranteed at the same time, also key in select material, high temperature resistance, high resistance to electromagnetic interference of the material to be preferred.
   (3) encoder replacement and maintenance is servo motor repair test technology in place, after all imports most of the servo motor is a standard format of communication.Early products can match with each other for incremental type, but a new generation of products has been formed their own different internal standard, different manufacturers have different standard mode, combined with pulse density is too large, in addition the encoder para have different algorithms, each brand products without sharing, increasing the difficulty of maintenance.
