SERVO MOTORS

Servo motors are variable position electrical motors which by design are complex and the re-manufacturing process requires specialized repair techniques.

Industrial servo motors range in both size and type. For example, motors can be constructed for either AC or DC power sources, designed with a variety of base RPM and max RPM speeds. DC motors typically have tachometer feedback control, whereas AC motors will typically be coupled with an encoder for precise control. They can be used to position ball screws, as well as a variety of geared devices.

We have expertise to repair all types and makes of motors. We understand the rigid specifications required for motors in the machine tool industry. Combining these elements with modern equipment for testing, balancing, winding, and cleaning a motor, the customer is guaranteed a quality job done right.

Our Quality Procedure For Repair

• Remove all shorts to ground
• Every device is tested both statically and dynamically to insure proper operation.
• Reduce stray electrical noise to the lowest possible level, if not eliminate it completely
• Tested for vibration, current draw, back EMF, torque, temperature rise, shaft runout, keyway condition, balance, magnetic field strength,acceleration rate, magnet position & mechanical integrity, brush spring pressure, correct brush compound, etc
• On low inertia motors, test start/stop ramps to verify acceleration capabilities
• Run-in for 24 hours (except for emergency expedites)
