PURPOSE:To readily inspect the adhered state of a duct in a vent hole of a coil conductor by forming a simulated slot extending axially to the end of a rotor body, and containing a simulated conductor having a simulated vent hole in the slot. CONSTITUTION:A simulated slot 14 is formed at the end of a rotor body 1, and a simulated conductor 15 which does not flow a current is detachably contained in the slot 14. The conductor 15 is retained by a wedge 7 fed through a movement preventing wedge 15 provided in the slot 14 at the radial end to retain the both axial ends by stoppers 17, 18. A simulated vent hole 6a which communicates radially is formed in the conductor 15. When the adhered state of dust in the hole 15a is inspected, the adhered state of dust in the hole of a rotor coil can be known. |
