Accu Electric Servo Motor Repair

Started in 1993, Accu Electric Motors Inc. is the premier repair facility of specialized servo motors. We are an ISO:9001 Quality Assurance and CSA explosion proof repair certified facility. Since our origin, we have successfully completed more than 3,000 Fanuc Servo Motor repairs. Our success as the go-to service provider can be attributed to our huge selection of OEM parts inventory and an excess of motor stock. Our stock includes the hard-to-find components like the endbells and replacement rotors. What is more is that all our Servo repairs attract a one year warranty.

Why Accu Electric Inc.

As the leading independent repair facility that serves the whole of North America, we are committed to offering only the best services in the servo motor repairs. To achieve this, we have brought together a team of factory trained technicians and equipped them with the tools they need to test every component to ensure you get a motor repair service that not just meets but one that exceeds the manufacturer’s specifications.

We are able to meet your unique motor repair needs thanks to a full-testing verification, load testing and round the clock emergency services. Our team also performs machine work as well as Fanuc servo motor rewinding in-house to ensure the highest standards possible. We service all Fanuc series motors.

Widing Analysis

With over $75,000+ invested in our winding analysis equipment, we catch

Winding can fail over an extended period of time, and without proper testing equipment, it is
hard to determine the cause.

  • Early phase to ground leakage
  • Phase to phase leakage
  • Resistance imbalance between phases
  • Inductance imbalance between phases
  • Impedance imbalance between phases
  • Phase angle imbalance between phases

Magnetizing is a key component with most stepper and pancake motors. Due to the type of magnets in stepper motors, when the rotor is removed from the stator the magnetic properties of the rotor are lost. Without the latest magnetizing equipment, most repair shops cannot repair these jobs.

Magnetizing in House - Servo Motor & Drive Repair

  • Capable of magnetizing N55 grade neodymium rare earth magnets
  • Fixtures for almost all sizes of rotors ready in stock
  • Required for pancake motor, and stepper motor repairs
  • Fixes many low torque issues with machines

Typically your servo, stepper or pancake motor incurring damage due to an overloaded system, causing a high current fault. This high current spike will cause the magnets in your motor to become demagnetized. Once demagnetized your motor may run, but with diminished torque. Under full load your system will fail. Another scenario in which damage is incurred is by opening the stepper or pancake motor. There is a specific air gap between the magnets in the stator and the rotor itself, if this air gap is lost (IE. by the removal of the rotor) demagnetization will occur.

By magnetizing the rotor after assembly, a high flux density is obtained that can be largely destroyed if the rotor is removed.

Thus by re-magnetizing your servo motor, stepper motor or pancake motor you will be assured that your motor will have the same torque output as it did when shipped from the manufacturer.

In this case BOSCH was unable to repair their own motor due to extreme damage. However, we were able to rebuild this motor in 24 hours to get the client up and running with manufacture matched specifications.

Full time dedicated machinists in shop allows us to repair industrial automation equipment with the highest quality standard. Not taking shortcuts we insure all our products are well fitted to manufacturer specifications.

  • In house dedicated machinist
  • Designs by mechanical engineers
  • New shaft installation and repair
  • Retrofitting in house

Since we are outfitted with a Machine shop, we do not need to send any work out, thus we keep our repair cost down, and are not dependent on someone else to complete repairs.

Often after repair of magnets and other rotor related faults, balancing is lost. Resulting in a vibrating noisy motor.

Our in-house balancing insures your motor will run smooth and quite the first time you plug it in.

One of the most effective measures for preventative maintenance is infrared technology. With it we can determine faults in areas such as:

  • Bearings and bearing housings
  • Overheating winding
  • Overcurrent
  • Hot spots in breakers, contactors, fuses, transformers & more.
  • Coreloss testing (as shown below)
