Send your NUM AC servo motor type BMH1152N1DF1C to Endeavor Technologies to be repaired right the first time!

Each NUM BMH1152N1BA1L3V motor is carefully evaluated by experienced technicians to determine if it is faulty.  After disassembly and cleaning, windings are checked with a digital surge tester, and all critical mechanical dimensions are measured with micrometers.  All test results become part of the permanent record of the motor in our database. 

If the motor winding has failed, it is replaced with a new assembly from the factory in Italy.  If a replacement isn't readily available, a new winding utilizing class H magnet wire and all class H insulation is installed according to the factory winding data and drawings.

Worn mechanical components are replaced with new components or re-furbished by one of our expert machinists.  Our machine shop is fully equipped with lathes, mills, and precision grinding equipment.  Rotating components are precision balanced on one of our Schenck Trebel hard bearing balancing machines.

During assembly, new bearings, seals, and any other required parts are installed, and the feedback device is aligned and tested.  Mechanical assembly tolerances such as shaft and flange runout are verified to be within NUM factory tolerances.  Finally the motor is test run, checked for noise, and vibration levels are recorded.  All the test data becomes part of our database, and a link to the final service report will be emailed to you upon request.

Don't risk having your NUM BMH1152N1BA1L3V motor "repaired" by unqualified personnel. Contact NUM USA or Endeavor Technologies about having it rebuilt to factory standards, with factory parts today!

Here are a few pitfalls unqualified "repair" shops fall victim to:

  • Improperly disassembling AMS series spindle motors, destroying bearing concentricity
  • Failing to adequately test static brake torque
  • Improperly aligning resolver feedback
  • Damaging digital encoder feedback using improper removal / installation equipment
  • Installing inadequately rated bearings in high speed spindle motors
  • Failing to complete immersion testing of IP67 servomotors. 

Only NUM U.S.A. and Endeavor Technologies stock the necessary, proprietary parts required to rebuild NUM motors.  Only NUM U.S.A. and Endeavor Technologies can retro-fit obsolete motors  with new encoders and update drive firmware.  Only NUM U.S.A. and Endeavor Technologies employ technicians trained at NUM Italy.
