When looking to collaborate with an industrial component repair company be sure to choose one that offers comprehensive repair and exchange services. These companies service motors and other components to make sure that the repaired parts are as good as buying a new replacement.

Managers of manufacturing units often ask what to look for when collaborating with a repair company for malfunctioning servo motors. The simple answer is – they must offer a comprehensive repair service. They must not only ensure satisfactory repair on all sorts of industrial machine components but also offer an exchange service. Repair of industrial machine parts often takes time and you cannot afford to wait for the malfunctioning motor to be fixed. The solution is to exchange the failing part for a replacement right away.

A reputable company will have an extensive repair process in place. All components are subjected to an in depth procedure to identify the problem and ensure flawless repair. They will provide adequate warranty on the performance of the repaired products that demonstrates the confidence they have in their remanufacturing ...
... skills.

When the technicians are on the repair job, you need to provide them with technical data sheets so that they may obtain the detailed specs for the servo motor or other components. Exchanging data sheets is important so the technicians can easily identify the root of the problem and fix the machine component as fast as possible.

When you send a servo motor for repair you can expect a static and dynamic check. This includes cleaning, washing and baking of the component, replacement of damaged parts, preventative replacement and thorough test runs.

The repair process begins with the Meg test to check if any moisture potentially grounded the motor. If this is the case, the motor is disassembled and the windings are washed and baked. Thereafter, machine evaluation is done to establish that all electrical and mechanical parts are performing up to standard. Rotor magnets are re-magnetized, brush holders replaced, front flange is remanufactured using the old flange and factory specifications, and windings are repaired.

A comprehensive repair process includes the checking of encoder covers, connectors and release voltage. Engineers ensure that all feedback devices such as hall sensors, tachometers, encoders and resolvers are functioning well. The quality of winding is verified and the stator is rewinded if needed. It is dipped in epoxy resin and baked to set it to the finish of the windings.

Now that the unit is reassembled and fitted with high grade sealed bearings double lip seals, O-rings, gaskets and connectors can be used to affect the overall performance of the motor. Double lip seals keep coolant from getting to the bearings, while sealed bearings prevent dirt from getting into the bearing races and protect it from liquid contamination as well.

When the technicians complete all this, they run the servo motor at full voltage on a drive to ensure that the industrial component is working flawlessly. A nameplate is sent along with the industrial component to provide all the relevant data.

Technicians of reputed companies hold expertise in Allen Bradley, Indramat, Modicon, Siemens and Fanuc servo motor repair. Regardless of the manufacturer of servo motor, they can perform their job in an impeccable manner. Whether it is CNC, robotics or automation, they can repair the components. They are extensively trained in troubleshooting and will identify the problem and have you up and running in no time.
