ECEE EOK testing procedures

AC Squirrel Cage Induction/ AC Slip-Ring (Wound Rotor) Motors:

  • Meggar test on Stator winding- Windings are washed and baked if necessary
  • Completely Disassemble motor and visually inspect for broken or missing parts as well as any visual defects in stator iron and rotor
  • Perform a Baker surge test on the stator windings
  • Perform open rotor (single phase) test as well as perform growler test on rotor
  • Core loss test the stator iron
  • Reassemble motor and prepare for shipment.

AC Synchronous Motors:

  • All above applicable tests
  • DC Drop Leg test on each pole piece

DC Motors:

  • Meggar test Field and Armature Windings (Advise if Low Readings)- Windings are washed and baked if necessary
  • Completely Disassemble motor and visually inspect for broken or missing parts as well as any visual defects
  • Test Interpoles and Field Coils
  • Test Bar to Bar on armature commutator
  • Inspect commutator for excessive or uneven wear
  • Reassemble motor and prepare for shipment.
