What We Do


Servo Repair

Servos have distinctive components that require specialized care, and Servo Repair International, Inc. is a specialized servo repair shop with the means to properly service all of the motor's parts--something that most average electric shops do not have. Avoid having to pull your servo out of your machine and repeat the repair process by sending your motor to our staff of fully trained professionals.

Servo Replacement

Extensive motor damage or unacceptable lead times may make replacement options a more intelligent and economical choice. Servo Repair International provides various replacement options for many OEMs. The older DC servo motors may be crossed over to newer products. We can also provide our own direct interchangeable DC servo motors as replacements. Many times just a simple feedback device crossover may be needed to increase turnaround time and better performance.

Remagnetizing

We can restore the lost torque of your existing servo motor by utilizing our in-house magnetizers and magnetizing fixtures. We build our own customized magnetizer stations and charging cores to cover the various diameters and pole configurations seen in today’s servo motors. With recharged rotors or field shells, motors are once again capable of providing the torque necessary for required machine performance.

DC Servo Crossover

Servo Repair International is able to crossover your existing DC servo motor from one manufacturer to another. SRI can replace your old, obsolete, DC servo motor by crossing over to new or refurbished motors with a one year warranty. If your manufacturer or OEM is on the DC Crossover List, SRI can crossover crossover your motors.

Why Do I Need a Servo Shop?

Can I repair my own servo motor? How about the motor shop down the street?

Before you try to repair your own servo motor or send it to your average electric motor shop you should know that servos have distinctive components that require specialized care.

DC servo motors use tachometers for feedback. Tachometers are like a small DC generator that the servo drive uses to monitor the servo motor's speed. You can test the tachometer's output with a voltmeter but the DC signal is as important as the voltage. An oscilloscope is needed to see the quality of the signal and to be sure it is not too noisy. A noisy signal can confuse the drive and cause the servo motor to run improperly.

A noisy signal can confuse the drive and cause the servo motor to run improperly.


AC servo motors can have a variety of feedback devices. Some will have a resolver, tach hall device, or an encoder. Some units can have a combination of the three. If your shop can't test these devices, read the various signals they output, or properly align them to the servo motor then they can't be sure the unit will function properly in your machine. Taking a chance that the feedback devices are okay without proper testing will usually lead to having to pull the servo out of your machine and starting over again. Avoid this scenario by sending your servo motor to a specialized servo repair shop who has the means to properly service all of their parts.

AC and DC servo motors both have permanent magnets inside. These magnets can weaken when the unit is disassembled. If your shop does not have the means to recharge these magnets, then even attempting to repair the servo motor may cause it to function improperly. Recharging the magnets found in servo motors requires a magnetizer; a piece of equipment that many shops that claim to repair servo motors either do not have or do not have the expertise to use for recharging servo motor magnets.
