AC Servo Motor Rebuild, Rewind, And Repair


The metal fabrication market industry in the United States is expected to grow steadily in the coming years. It has seen technology advancement such as robotic automation and software integrations to support the momentum of the industry. Despite the various innovations, a fundamental component such as the AC servo motor is still decisive in the productivity of metal fabrication.

Common Causes of AC Servo Motor Failure

As with any electrical components, an AC servo motor is subjected to degradation and outright failure along the line. Regardless of the industry you are in, such failure could affect operations and lead to financial losses. There are various causes that may contribute to the breakdown of an AC servo motor and they can be broadly categorized into mechanical, electrical and electronics fault.

One of the common mechanical faults is the contamination of oil and grease inside the motor or the brake. Such contamination can lead to complicated issues that affect the bearings, winding and the electrical components of the motor. It is also inevitable that bearings wear off after prolonged usage.

Electrical faults such as motor winding failure and degradation of components like capacitors can happen over time. Issues with the power supply can also lead to voltage spikes and damage the internal electronics component. There are occasions where the AC servo motor failure is caused by mere improper installation that results in off-positioning and extremely tight belts.

AC Servo Motor Rebuild, Rewind and Repair

When the AC servo motor driving your equipment breaks down, the logical course of action is to have it repaired or rebuilt. In most cases, it is more economical compared to replacing with a brand new motor. For example, bad winding can be addressed by rewinding the copper coil. Regardless of the issues, every repair process is handled meticulously by our technicians based on a systematic procedure.

The AC servo motor would undergo preliminary inspections to identify the cause of failure. At this point, we will determine if your faulty AC motor could be repaired and restored to its full functional condition. Once our clients agree with the cost of repair, we would then proceed with replacing or repairing the faulty components of the AC servo motor. This process often includes dismantling the motor completely and thorough cleaning and inspections of the internal parts. These are all performed by highly trained and experienced repair technicians with the aid of sophisticated repair equipment.

As the repair process completes, the motor is then rebuilt and assembled with new seals and gaskets. Our repair team ensures the motor is properly sealed and no coolant or oils can seep into the motor. Before we give you the call that your motor is ready, we put it to a stringent test to ensure that it is performing reliably. Once we are satisfied that it is as good as new, we will deliver the repaired AC servo motor back to you.

Precision Electric Offers You Peace Of Mind

The worst thing that could happen with a newly repaired AC servo motor is for it to fail again shortly after it is put into operation. While our repair team has a positive track record, Precision Electric is more than happy to offer 12 months in-service warranty that only takes effect after your repaired motor is commissioned for operation. Thats how confident we are with our repair services.
