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 / 3 or E, a test voltage V test applied to an armature winding of the inverter drive rotating electric machine is set to V test = ± ‹ E / 3 or V test ' = ±·E, respectively, provided that ± (= t inv /t sin ), if an insulation thickness t sin of the sine wave drive rotating electric machine is t sin , and an insulation thickness of the inverter drive rotating electric machine is t inv , thereby conducting a test on any of an AC voltage-current characteristic, an AC tan´ characteristic, and an AC partial-discharge characteristic. |
