摘要： A slip ring cooling device for electrical rotary machine comprises a plurality of closed chambers axially extending in the peripheral portion with intervals therebetween in the peripheral direction, and an annular passage at one side. The closed chambers each are defined by the surfaces of holes made in the slip ring so as to axially extend at the peripheral portion of the slip ring. The axially extended holes have open ends and closed ends. The annular passage is fluidly connected to each of said open ends so that said closed chambers communicate with said annular passage. A volatile liquid poured in said passage is distributed uniformly to each of said closed chambers by centrifugal force applied thereon upon the rotation of the slip ring. The distributed liquid is evaporated by the slip ring and brushes contacting the slip ring to form vapor. The vapor is transferred to the lower temperature portion by the pressure difference to be cooled and condensed, whereby the slip ring is cooled.

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： At least one circumferential slot is provided at a predetermined axial position on an armature core so as to cross axial slots receiving a plurality of coil sides of an armature winding and to communicate adjacent axial slots, and the plurality of coil sides to be generally mounted in the same axial slot are partially shifted from one slot to an adjacent one through the circumferential slot so that the coil sides of the armature winding are partially arranged to extend through adjacent slots at a fixed, predetermined circumferential distance. In this manner, the generation of commutating spark is substantially prevented and the commutating performance is improved.
