PURPOSE:To improve the detecting accuracy of a rotary electric machine and to facilitate the inspecting work of the machine by arranging a rotary disc formed in a specific diameter in the intermediate between a rotor and a bearing to form a gap between the disc and the inner periphery of a frame and to enclose the end surface of the bearing. CONSTITUTION:A detector 26 is overhung at the end of a body, and a rotor 27 is engaged with the end of a rotational shaft 22 which is projected through a bracket 3 through a cylindrical boss 28a of a rotary disc 28. A stator 29 which encloses the rotor 27 is engaged with the inner periphery of a cylindrical frame 20, which is engaged directly to the end of a bearing housing 3a. This disc 28 is formed to be equal or larger than in outer diameter the rotor 27 and smaller than the outer diameter of a bearing 1. Further, the disc 28 is arranged at the intermediate position between the rotor 27 and the bearing 1 at an interval (g) between the disc and the inner periphery of an inward flange 20b of the frame 20 to enclose the end of the bearing 1. |
