  • Patent number: 5969531
    Abstract: The inspection apparatus for inspecting performance of a structure such as stator windings of an electric rotating machine of the invention comprises a probe including a measuring element, an arm unit and a cylinder face circumferential moving apparatus. The arm unit has an arm link section supporting the probe (mainly comprising a leading end link assembly and an arm posture keeping mechanism), an arm housing section (mainly comprising a guide rail) regarding driving of this arm link section, and an arm driving mechanism. The arm driving mechanism causes the leading end link assembly to project from the guide rail at an angle toward a measuring position side of the stator windings relative to the axial direction of the rotor unit, while causing the arm link section to travel along the guide rail. The arm posture keeping mechanism is provided with a link wire and a spring, and maintains a straight arm posture of the leading end link assembly after projection from the guide rail.

  • Patent number: 5946793
    Abstract: At a time of disassembling and assembling stator windings of a dynamo-electric machine in which the stator windings fitted in slots formed to an inner periphery of a stator core disposed inside a stator frame are disassembled therefrom and conveyed outside the stator core successively and new stator windings are then conveyed into the stator core and assembled into the slots successively, a mounting apparatus is arranged between the slot and an inside conveyer for mounting the stator winding into the slot. The stator winding is disassembled from the slot into which the stator winding is inserted while receiving and holding the stator winding by a receiving member provided for the mounting apparatus. The stator winding is then moved to the inside conveyer from the mounting apparatus and then conveyed from the inside conveyer to an outside conveyer.
