Fanuc AC Spindle Motor Repair at Repair Zone.

If your machine has stopped working or is acting up, and you have pinpointed the issue to your spindle motor, you can send it to Repair Zone for a free evaluation.

We can quickly diagnose the issues you are having through a myriad of testing procedures.
We test the ohms with a Megger tester to see if the stator is good or is grounded.
During disassembly:
• We find a cracked fan cover that needs replacement.

• The fan assembly is then taken apart; the fan motor is surge tested to check the strength of the insulation.

• We check the gap of the speed sensor

• We test the off-set

• Using a digital oscilloscope, the amplitude is measured.

• We then remove the speed sensor wheel by applying heat, along with opposite pulley end bell.

• The rotor is removed from the stator – and the bad bearings removed.

The technician visually inspects the motor windings, and the bore of the stator for obvious trouble spots. The stator is then surge tested as well, where all 3 phases are tested for dielectric strength of the insulation. In this case, the stator was good.
The entire unit is washed thoroughly using both a high-pressure sprayer and a parts washing machine, removing all contamination that had built up. It is then baked over-night in our oven.

During assembly, new bearings are installed; the stator is megged again after the wash and bake; rotor is put into place; motor housing and end bell are installed. Final testing occurs as amplitude is measured again.

Next, the spindle is connected to a Fanuc amplifier and ran in both directions, stopping and starting multiple times until testing is completed. The speed sensor is tested for proper specs after assembly as well.

Finally, the completed unit is returned to you with a 1 year warranty.
