1. In a dynamoelectric machine including a stator having a main axis and having a recess formed therein being approximately circular cylindrical relative to the main axis, and a rotor being approximately circularly cylindrically disposed relative to the main axis and being rotatable about the main axis in the recess, defining a gap in the recess between the stator and the rotor,an instrument carrier for inspecting the dynamoelectric machine, comprising:

  • an instrument carrier axis being brought into coincidence with the main axis during inspection;

    a frame part annularly surrounding the instrument carrier axis;

    inspecting means being mounted on said frame part; and

    a multiplicity of rollers being mounted on said frame part, being mutually offset as seen in a plane perpendicular to the instrument carrier axis, and being rotatable about axes of rotation aligned substantially perpendicular to the instrument carrier axis.
