• Feedback Tests (Tachometer/Encoder)

Motor Disassembly

• Bearing and seal sizes are recorded
• Bearing fits are measured on shaft and End bell
• Brake torque is measured as well as resistance and Meg Ω
• More winding tests are performed (Surge and HiPOT tests)
• Stator is then washed and baked in oven
• Magnets are inspected for cracks or if loose on shaft
• Encoder is tested with either (Heidenhain PWM20, Sick PGT-11, or Mitchell Electronics equipment)

Assembly
