Looking for the authority on Siemens motor repair? At Endeavor Technologies, we avoid using the word “repair” because we specialize in rebuilding. We don’t simply fix what is broken–we return old, damaged, and worn out spindle motors and servo motors to like-new condition.
In a hurry? Check our inventory of completely rebuilt Siemens servo and spindle motors. If you don’t see what you need, give us a call at 630.562.0300 or send us an email to see if we can build it quickly.
Third Party Siemens Motor Repair
We operate independently of Siemens, and there can be advantages to using a third party for your Siemens servo motor and spindle motor repair needs. We have invested extensively in creative rebuild techniques, spare parts inventory, test stands and diagnostic tools to service Siemens motors—particularly obsolete motors which Siemens is increasingly unable to service.
Repairing Your Siemens Spindle Motor or Servo Motor
Rebuilding motors requires components. We stock resolvers, encoders, brakes, connectors, fan motors, and other components. Siemens spindle motors require bearings that can operate at higher speeds than ordinary electric motor bearings. We have an extensive stock of radial bearings with special features designed for use in machine tool motors.
Siemens motor repair may require replacing the shaft if a bearing has failed catastrophically or if the output shaft is badly worn. The experts in our machining department will fabricate a new shaft, and precision grind all the critical diameters to factory tolerances.
If the motor winding has failed, our winding department rewinds it with class H insulation. This is done while carefully observing the original factory winding specifications. We can also upgrade your built-in motor spindle winding with our Epox-E-Pak insulation system.
Before being assembled, all spindle motors are dynamically balanced . Balancing is a critical aspect of rebuilding any spindle motor. It is just as important to measure and monitor the amount of vibration the motor produces during full speed testing. Learn more about our balancing and vibration testing capabilities.
Siemens servo motor repair may require rebuilding the magnet rotor. Endeavor Technologies offers complete magnet rotor rebuilding for Siemens servo motors.
After assembly, your spindle motor or servomotor will be run through a break-in period to full speed. This is necessary to test the vibration levels and to ensure that the grease is properly distributed inside the bearings to prevent overheating. Typically this done using one of our test stands built with Siemens controllers. Siemens has supplied motors with a variety of encoders and resolvers. Therefore, we have invested in a variety of diagnostic tools to test and align these devices. Learn more about our testing procedure.
Service reports as well as failure reports are available on request.
Support AND Service
Endeavor Technologies offers the highest service and support for Siemens spindle and servo motors because of our commitment to test equipment, training, and inventory.
If your Siemens motor was “repaired” by a less experienced repair shop and still doesn’t work, or failed pre-maturely, it’s not too late! Send your Siemens spindle motor or servo motor to us for rebuilding and comprehensive testing.
