Abstract
A wedge measuring apparatus comprising a measuring head, capable of being inserted between a stator and a rotor of a revolving electric machine, for testing a coil-urging state of wedges inserted in a slot, and a mechanism for moving the measuring head in the longitudinal direction of the stator and the circumferential direction of the rotor. A test for the coil-urging state is performed to prevent a coil from extending from an opening in the radial direction. In this case, the coil is inserted in a slot having the opening formed in a stator wall surface opposite to the rotor, and the slots are formed along the axial direction of the stator core.
