ABSTRACT:
A dynamoelectric machine includes a stator and a rotor. The rotor is approximately circularly cylindrically disposed relative to a main axis, is rotatable about the main axis and leaves a gap in a recess of the stator which is approximately circularly cylindrical relative to the main axis. An instrument carrier for inspecting the dynamoelectric machine can be inserted along the main axis into the gap and moved there. The instrument carrier includes a frame part which approximately annularly surrounds the main axis and on which a device for carrying out the inspection can be mounted. A multiplicity of rollers are mutually offset, as seen in a plane perpendicular to the main axis, and each is mounted on the frame part so as to be rotatable about an associated axis of rotation. The axis of rotation is aligned essentially perpendicular to the main axis. The instrument carrier can be inserted into the gap without prior removal of the rotor, and can be equipped as desired with instruments and auxiliary devices for carrying out the inspection. The instrument carrier can be moved in the gap without the risk of tilting and jamming, since it is directly supported on the stator.
