Your Mitsubishi motor HA-A20 will be carefully evaluated by experienced technicians to determine if it is faulty.  Motor Ke (back e.m.f.), brake torque, and encoders will all be tested with a variety of diagnostic instruments.  After disassembly and cleaning, the windings will be checked with a digital surge tester, and DC hi-pot.  Critical mechanical dimensions will be measured with micrometers, and all test results become part of the permanent record of the motor in our database. If the motor winding has failed, the old winding will be carefully reverse engineered before being stripped with a mechanical stripping method that prevents any damage to the insulated core. A new winding utilizing class H magnet wire and all class H insulation will be installed. Worn mechanical components will be fabricated or re-furbished by our expert machinists.  Our machine shop is fully equipped with lathes, mills, and precision grinding equipment.  
Rotating components will be precision balanced on one of our Schenck Trebel hard bearing balancing machines. New bearings, seals, and any other required parts will be installed during assembly, and the feedback device will be aligned and tested.  Mechanical assembly tolerances such as shaft and flange runout will be verified to be within factory tolerances.  
Finally the motor will be test run, checked for excessive noise or temperature, and vibration levels recorded.  All test data becomes part of our database, and a link to the final service report will be emailed to you upon request.

"The personnel at Endeavor Technologies, Inc. know more about servicing Mitsubishi motion control motor products than any other rebuilding company." Mitsubishi Electric Automation

The best of everything--fully tested to the factory standard. No one offers better service and support for Mitsubishi spindle and servomotors because no one else has made the same commitment to test equipment, training, and inventory. Our simulators incorporate a wide variety of Mitsubishi amplifiers and MELDAS CNCs, our personnel have been trained at the factory in Japan, and our ongoing relationship with Mitsubishi Electric Automation ensures that we have access to the latest technical data and specifications.

We service nearly every Mitsubishi servomotor. Including those with type numbers beginning:

HA          HC          HD          HF           HP

We service all AC & DC  spindle motors.   Including those with type numbers beginning:

SDN       SE           SJ

Our capabilities are always expanding, so call or email us if you don't see your product listed.

Unlike your local repair shop, we have the equipment and training to correctly program the latest digital encoders.  Our inventory includes tens of thousands of dollars of new encoders, factory supplied bearings, fan motors, terminal blocks, and other parts allowing us to remanufacture your motor to new condition.

Our test procedures are the best and most thorough in the industry because we use Mitsubishi CNCs, and servo/spindle amplifiers to run-in your rebuilt motor.  Many "repair" shops can't run servo motors at all, and can't run spindle motors at full speed. A motor rebuilt by ETI has been test run, closed loop with the encoder, to full speed.  Water cooled and / or oil-air lubricated motors are tested for extended periods of time with cooling and lubrication systems similar to those used on machine tools. Bearing temperatures and vibration levels are monitored and verified to be within factory specification before the motor is returned.
