Method for testing an inverter drive rotating electric machine

摘要

With a rotating electric machine testing method for applying a test voltage to an armature winding of the rotating electric machine to thereby test insulation performance of the armature winding, in the case where a rated voltage of the armature winding of the rotating electric machine is E, and an insulation test voltage of an armature winding of a sine wave voltage drive rotating electric machine at the rated voltage E is E/√{square root over (3)} or E, a test voltage Vtest applied to an armature winding of the inverter drive rotating electric machine is set to Vtest=α·E/√{square root over (3)} or Vtest′=α·E, respectively, provided that α(=tinv/tsin), if the insulation thicknesses of the sine wave drive rotating electric machine is tsin and of the inverter drive rotating electric machine is tinv, thereby conducting a test on any of the AC voltage-current characteristic, AC tan δ, and AC partial-discharge characteristics.
