PROBLEM TO BE SOLVED : To provide an armature inspection method of a dynamo-electric machine capable of improving detection accuracy of a true short-circuited armature by reducing an influence of a disturbance to short-circuit determination of winding.SOLUTION : Existence of a short circuit such as a rare short of a winding coil 4 is determined from a plurality of pairs of output waveforms based on an inspection pulse acquired from between terminals of the winding coil 4 connected to a commutator segment 5a of an adjacent or counter electrode, for example, from the degree of dispersion in the whole section of the segment 5a.COPYRIGHT : (C)2007, JPO&INPIT
