Rebuilding SEM Equipment Excellence

Motor Type:


Exchange: 5 - 7 days

 Your SEM motor MT30F4-45 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.

Endeavor Technologies completely remanufactures  SEM servomotors. Failed windings, broken shafts, seized bearings, non-functioning brakes, and bad resolvers are no problem because of our extensive in-house capabilities, parts inventory, and supplier network.  

Our test procedures are the best and most thorough in the industry.  Many "repair" shops can't fully test servomotors.  An SEM motor rebuilt by ETI has been test run, closed loop with the encoder or resolver, to full speed.  Each rebuilt motor is checked to ensure that it conforms to the factory assembly tolerances, not just an industry norm for general purpose motors. Slippage is a common problem with brake motors.  Each SEM brake motor is torque tested after being rebuilt to ensure it holds at least the factory specified torque.
