Cracks in end bells or covers

Job Ticket

We complete to full write up off all motor data

Including

All winding tests (Resistance, Meg Ω, Continuity)
All bearing sizes
All seal sizes
Brake torque tests (Record Torque, winding resistance)
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

New bearings are installed
New seals are installed
If required, new windings are impregnated
Brakes are rebuilt or replaced depending on manufacturer design.
Rebuilt or New encoders are installed and aligned using:
(Heidenhain PWM20, Sick PGT-11, or Mitchell Electronics equipment)

Rotor Balancing and Testing

Rotor is run through a full vibration diagnostic

Run Testing

Every Motor is Run for a minimum of 1 hour using one of our drives.
We use Siemens S110, S120, IndraDrive, AB Kinetix 300, Yaskawa 7, and AMC drives
