Procedure for sending in a Servo Motor Repair:

  1. As we receive your shipment, we assign an RMA tracking number
  2. After doing a thorough inspection we give the estimate on cause of failure, what’s required to get it back up and running, and quote you the repair
  3. After approval motor the servo motor is moved forward to the technical team for repair, where the technical team will take care all the mechanical, electrical or electronic faults and failures in motor.
  4. After repair and reassembly the lead technician will adjust the alignment angle and run-test the motor on the original OEM drive, not a standalone universal drive as our competitors. This insures the motor works exactly how it would in your system. Our vast investment in harnesses and drives makes this process quick, safe, and cost effective for you to get your machine back online fast.
  5. Once completed the motor is packed, with foam in a secured box for shipping, and customer is sent the tracking number.

Company Overview

Repair vs. Replace

Should You Repair a Failed Servo or Replace one?

A failed servo motor is never a good thing. Aside from the expenses of halting production and the costly downtime of finding the right solution, there’s another important question to ask: Should I repair a failed servo or simply buy another motor? The correct answer to this question can mean the difference between a lengthy and expensive situation and a prompt return to production. When deciding between repairing or replacing a servo motor, consider these factors:

  • Why did the motor fail? What were the symptoms?
  • Is there a spare unit on hand that can be put into service?
  • Is the machine down? What is the cost of continued downtime?
  • What is the cost of a new motor? Is it immediately available or is there a lengthly lead-time until it can be delivered and put into service?
  • What is the warranty (in-service) for a repair?
  • Can you find a servo repair vendor willing to provide a free quote? Can they do so in a timely manner?
  • Is the repair vendor reputable? How long have they been repairing servo motors?
  • Even if the repair is more than 50% the cost of buying a new motor, can the machinery be running more quickly than buying new?
