    Motor nameplate data is recorded

  2. Inspection

    A visual inspection of any damage to the motor.

    We check for
    • Damaged Leads/Terminals
    • Worn output shaft/keyways
    • Cracks in end bells or covers
  3. Job Ticket

    We complete to full write up off all motor data

    • All winding tests (Resistance, Meg Ω, Continuity)
    • All bearing sizes
    • All seal sizes
    • Brake torque tests (Record Torque, winding resistance)
    • Feedback Tests (Tachometer/Encoder)
  4. 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)
  5. 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)
  6. Rotor Balancing and Testing

    • Rotor is run through a full vibration diagnostic
  7. 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
  8. Service Report

    • A Final 3-page Service Report is filled out
    • Pinout diagram for power and feedback is provided
    • Brake torque is recorded a final time for our Service Reports
    • A photo of nameplate and motor is attached
    • A motor tag is installed on motor with QR code linking Service Report and Job Histories
    • If requested, a YouTube link is attached to the service report of motor
