Here are a few pitfalls unqualified "repair" shops fall victim to:

• Improperly disassembling AMS series spindle motors, destroying bearing concentricity
• Failing to adequately test static brake torque
• Improperly aligning resolver feedback
• Damaging digital encoder feedback using improper removal / installation equipment
• Installing inadequately rated bearings in high speed spindle motors
• Failing to complete immersion testing of IP67 servomotors.
