    • A method of adhering in advance a soldering material to a location on each of a plurality of claw-shaped portions of a commutator at which a winding for the armature of an electric motor is to be electrically connected thereto, for ensuring a strong and reliable electrical connection between the windings and the claw-shaped portions.A plurality of narrow grooves are defined in the claw-shaped portions and the narrow grooves are charged with molten soldering material, which solidifies therein. The thus-solidified soldering material is thereafter re-melted by heat produced at the time of resistance welding of the windings to the claw-shaped portions to thereby reinforce the electrical connection between the claw-shaped portions and the windings and to prevent an increase in the electric resistance between the windings and the claw-shaped portions.
    • 预先将焊接材料粘接到换向器的多个爪形部分的位置上的方法,在该位置上,用于电动机的电枢的绕组将与其电连接,以确保强而可靠的电气 绕组与爪形部分之间的连接。 在爪形部分中限定有多个窄槽,并且在其中固化的熔融焊料充满窄槽。 这样固化的焊料随后通过在线圈对爪状部分进行电阻焊接时产生的热量再次熔化,从而加强了爪形部分和绕组之间的电连接,并且防止了增加 绕组与爪状部之间的电阻。

    • A brush holding device of an "easy-to-assemble" type disposed between a yoke and an end frame of a motor. The device has a brush holder formed in one body from an electrically insulating material to include an annular-type field winding fixing frame, a brush holding stay having a plurality of brush chambers thereon, each of the brush chambers having at least an opening on the side of the end frame, integral connecting portions annularly connecting the spaced brush chambers therebetween, an insulating plate member having relatively rigid body portions to cover the openings of the brush chambers and relatively flexible portions connecting the body portions therebetween, and means for fixing the insulation to the brush holders by deforming the flexible portions of the insulator toward the brush holders. The aforementioned annular fixing frame has a plurality of flanges radially outwardly extending from the outer periphery thereof by which the annular frame is circumferentially axially aligned with the yoke. Consequently, the brush holding device is able to be rigidly held between the yoke and the end frame without using a bolt while establishing a good alignment of the device in the circumferential and the axial direction.
    • 设置在电动机的轭架和端框架之间的“易于组装”型的电刷保持装置。 该装置具有从电绝缘材料形成在一体中的电刷架,其包括环形场磁绕组固定框架,其上具有多个电刷室的电刷保持支架,每个电刷室至少具有一个开口 端部框架侧的一体连接部分,环形地连接间隔开的刷室的绝缘板部件,具有相对刚性的主体部分的绝缘板部件,以覆盖刷腔的开口和连接其间的主体部分的相对柔性部分,以及用于固定绝缘体的装置 通过使绝缘体的柔性部分朝着电刷架而变形到电刷架。 上述环形固定框具有从外周向径向向外延伸的多个凸缘,通过该凸缘环形框架与轭架沿周向轴向对准。 因此,能够在不使用螺栓的同时将电刷保持装置刚性地保持在轭架和端框架之间,同时在周向和轴向方向上确保装置的良好对准。
