The evaluation of the servo motor during the repair process includes thorough checking of sundry electrical and mechanical parts on the motor. The entire unit is cleaned, washed and baked, and replacement of damaged components is done. Finally, the technicians ensure that the feedback components are functioning efficiently.

It is imperative for manufacturers to collaborate with repair companies that can that can effectively repair their malfunctioning or broken down machines. Skilled engineers working with a noted repair company will ensure that the repaired component works as efficiently as a new one.

When you send a malfunctioning servo motor or other component to the industrial repair company, it will be subjected to an evaluation process in order to detect the cause of the problem. The engineers will make sure that the static or dynamic parts of the component meet the factory specifications. Using technical data sheets, they will obtain finite specifications for that specific motor. A well-implemented repair is the difference between a motor that just works and one that performs outstandingly.

In the ...
... repair zone, a motor is checked for static and dynamic parts. The entire unit is cleaned, washed and baked, and the damaged components are replaced. Thereafter, preventative maintenance and replacements are done. Finally, complete run testing is done.

Meg test is the first test done in the repair process. This is performed to check if moisture could have been the cause of grounding of the motor. If this is the reason, the servo motor is disassembled and the windings are washed and baked. After this process is done, the Meg test is performed again. If the there is still moisture in the motor, the process is repeated once more.

The evaluation process includes thorough checking of sundry electrical and mechanical parts on the motor. It includes the housing fits, bearing fits, worn output shafts, and corroded and broken flanges. Any detected problems during this process are taken care of. The front flange is remanufactured, the brush holders are replaced, the windings are repaired and the rotor magnets are re-magnetized. Connectors, encoder covers and release voltage are checked in the in-house machining center. The engineers also ensure that the feedback components – resolver, encoder, tachometer, hall sensor – are all functioning efficiently. Finally, they do independent torque testing to check the brake assemblies.

The surge test is another important step. The stator is rewound, dipped in epoxy resin and then baked. The next step is to reassemble the motor. After the assembly is done, the motors are fitted with O-rings, gaskets, double lip seals in the front flange and high grade sealed bearings, which prevent dirt from getting into the bearing races.

After all the testing is done, the servo motor is run on a drive, allowing the engineers to ensure that all necessary repairs have been done correctly. The motor is run at full voltage to test its optimum capability. Then it is dispatched to the owner along with all relevant data.

A top-of-the-line company will usually deliver a wide range of services for many differnet industrial components. Fanuc, Indramat or Allen Bradley repair and service, they will be able to help you during any downtime. The standard amount of time for repair services is 3 to 5 days once the component is received in the warehouse. If you wish to have the item repaired quicker, you can request for rush services.

Such companies usually offer field services as well where they can come on site for repairs and services. For preventative maintenance such as installation and removal, testing and analysis, and repair, the technicians will come directly to the client’s facility. Getting a repair on-site is as easy as filling out a form on a website or giving the company of your choice a call.
