What is Remagnetizing?


 
'Remagnetizing' is a company term that SRI uses to explain that we are able to magnetize permanent magnet motors back to original levels and return a motor to its OEM specifications. What does that mean? Using this process, your motor can regain its maximum torque output.

What Causes Demagnetization?

There are multiple reasons why a motor might become demagnetized:

An incorrectly adjusted machine
Design flaw(s) (e.g. Incorrect Cooling…)
Unsatisfactory operating environment
Unforeseen mechanical or natural occurrence(s)

What Happens When My Motor Demagnetizes?

Demagnetization can result in several problems:

Loss of torque
Difficult speed control
Higher energy usage
Dropped magnets
Other unwanted issues

The Wrong Solutions

 

Most of the time, taking your servo motor to a normal repair shop will result in remedies that are costly solutions to a simple motor problem, if they even fix the issue at all.


Gluing Dropped
Magnets

Most normal repair shops will glue dropped magnets back into the frame shell or rotor. This doesn't actually solve the problem; the magnets are still weak and cannot function at peak efficiency.


Replacing
Parts

Many times shops will replace old DC frame shells, tachometer magnets and AC rotors with new ones. These parts have a high cost and are often not needed.


Replacing
Magnets

Replacing demagnetized magnets with new fully-charged magnets has a high parts and labor cost that can be avoided by remagnetizing the existing magnets in your motor.


Replacing
the Motor

Many times, a shop will tell the owner that their motor is too old or that it would be cheaper to replace the entire thing. This the highest-cost option, and one that you may not need to consider.

We Do It the Right Way


Servo Repair International, Inc. can restore the lost torque of your existing 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. In just a few seconds, a motor is brought back to its maximum torque potential by recharging the existing magnets to their specified levels. With recharged rotors or field shells, motors are once again capable of providing the torque necessary for required machine performance.

Ask your present repair shop if they have their own magnetizer and fixtures for remagnetizing motors. If not, then you are settling for a lower quality repair or paying unnecessarily higher repair costs.

We remagnetize DC and AC permanent magnet motors as standard procedure during the evaluation and repair processes. Our magnetization service however, does not end there. If the opportunity exists to speak with the end user, we can offer information on preventing future demagnetization occurrences; thereby preventing downtime and costly repairs.

Replacement Capabilities


Sometimes having a servo motor repaired is not the best option. 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 intercahangable DC servo motors as replacements. Many times just a simple feedback device crossover may be needed to increase turnaround time and better performance.
