PURPOSE:To contrive the common use of the component parts of motors when motors of different output capacities are constructed by engaging a pair of casings of cylindrical shape with bottom so that the openings of the casings are superposed and providing projections on the outer periphery of the inside casing. CONSTITUTION:A pair of casings 1, 2 of cylindrical shape with bottom are engaged so that the openings are opposed in such a manner that one of the openings is disposed inside and the other is disposed outside, and bearings 6, 8 are held by swelled parts 15, 16 formed substantially at the center of the side plates 5, 6 of the respective casings 1, 2 and auxiliary supporting members 17, 18. A stator 4 having a coil 3 is rigidly engaged with the inner surface of the inside casing 1, and the rotational shaft 10 of a rotor 9 is rotatably supported via the bearings 6, 8. Collars 1a, 2a are projected at the openings of the respective casings 1, 2, the projected part of the wheel bank 1b or projection 1b' is formed on the circumferential direction at the engaged superposed part of the outside casing 2 at the outer periphery of the inside casing 1, thereby allowing the axial centers of the casings 1, 2 to coincide. |
