Your Okuma motor BL-MC200J-20TB will be carefully evaluated by experienced technicians to determine if it is faulty.  Motor Ke (back e.m.f.), brake torque, and encoders or resolvers 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.  If you've had your motor "repaired" and it still doesn't work, it's not too late--send it to Endeavor Technologies to be rebuilt to factory specifications today!
Back to Okuma listing...

The best in the industry.   Endeavor Technologies took advantage of a unique opportunity with Okuma America to establish the most comprehensive test protocols and specification database for Okuma motors outside of Japan.  Unlike your local "repair" shop, we have simulators allowing us to test run Okuma servomotors and spindle motors after rebuilding them.   We inventory  thousands of dollars of spare parts especially for Okuma including connectors, cooling fans, terminal boards, resolvers, and encoders, brake components, and more--even motor shafts.

Each spindle motor or axis motor is checked to ensure that it conforms to the factory assembly tolerances, not simply an industry standard more suited for general purpose motors. Vibration levels are verified at full speed during each test run to verify that it conforms to Okuma's specification, not a general standard acceptable for non-machine tool duty motors. Slippage is a common problem with brake motors. Every Okuma brake is torque tested after being rebuilt to hold more than the factory specified torque.

Magnetizing weak magnet rotors is a critical aspect of rebuilding many servomotors.  Endeavor Technologies invested in custom built magnetizing equipment for Okuma BL servomotors. Some of the BL magnet rotors develop problems that are very troublesome to diagnose. Our test protocol and specially developed rebuild technique ensure that we find and correct these faults.

Don't take a chance having your motor "repaired"!  Send it to Endeavor Technologies where it will be rebuilt to factory specifications, and fully tested.
