摘要： An electric rotary machine is provided with a stator having a stator core of laminated iron plates with a given lamination thickness in an axial direction of the machine and a stator winding wound around the core and a rotor rotatably disposed inside the stator, having a rotor core and a rotor winding. The axial length of the stator core is selected with respect to that of the rotor core in such a way that, when the rotor is thermally extended, the end of the rotor core never extends beyond the end of the stator core. With such a constructional arrangement, there is eliminated an excessive temperature rise at the ends of the stator core, and prevented an insulation deterioration of the stator winding and the burning of the stator core.

摘要： A brush holder for dynamo-electric machine has the following parts: a brush making sliding contact with the surface of a rotary collector; a stationary holder part fixed to the stationary part of the dynamo-electric machine opposite to the collector; and a detachable holder part detachably secured to the stationary holder part and holding the brush when separated from the stationary holder part, the detachable holder part being provided with a retainer that clamps the brush when the detachable holder part is separated from the stationary holder part and unclamps the brush when it is attached to the stationary holder part, the brush clamping portion and the portion of the retainer therearound being coated with a coating film of a material having a friction coefficient smaller than the material of the retainer. This arrangement obviates various unfavorable phenomena such as jumping of the brush, sparking on the sliding surface, cracking in the brush and so forth.

摘要： A rotor for electric rotating machines has a plurality of salient poles arranged in spaced relation in axial direction on the outer periphery of the rotor rim. Adjacent salient poles have opposed slots in the axial direction, into which a shielding member is fitted to bridge between said adjacent poles. The shielding member includes a plurality of rod members fitted over the entire length of said slots to extend across said opposed slots. While the rotor is running, the centrifugal force acts on each of said rod members thereby pressing the rod members against the outer periphery side wall of the slot. As a result, the centrifugal force is dispersed substantially uniformly over the entire length of the slot wall.
