Spindle Motor Repair

The spindle motor runs at the highest speed and is the most expensive motor on the machine. Ignored vibration, overheating or bearing noise causes permanent damage. We address the mechanical and electronic faults together and deliver under warranty after dynamic balancing.

Spindle Fault Symptoms

• Vibration and overheating/noise during operation
• Metallic bearing noise
• Unstable speed, cannot reach target RPM
• Spindle drive alarm

Our Spindle Repair Process

We check bearings, winding, encoder and balance; replace bearings, rewind and precision-balance as needed, repair the spindle drive and verify vibration and temperature under load. See our services.

Frequently Asked Questions

My spindle vibrates — what causes it?

Usually worn bearings and lost balance, solved by bearing replacement and dynamic balancing.

Is replacing bearings alone enough?

Usually not; balance must be redone and the encoder calibrated.

Do you repair the spindle drive too?

Yes, we repair motor and drive together and test under load.

Is the repair warranted?

Yes, delivered under warranty after balancing and testing.
