    摘要: An electrical machine, preferably a blower drive mechanism for a motor vehicle, having a shaft which is supported in at least two bearings with a specified axial play; a cylindrical bearing is secured in a bearing seat of an end shield and rests directly on the bearing seat. The cylindrical bearing has a cylindrical outer circumference, and the bearing seat is a sleeve with a cylindrical inside diameter, into which sleeve the cylindrical bearing is secured with a press fit on the outer circumference and is held axially in the bearing seat by the thus-attained frictional engagement. This has the advantage that more-precise adjustment of the longitudinal play of the armature is possible. Moreover, no additional components such as retaining springs are necessary.

    摘要: A twisted pair of wires is produced by drawing two insulated wires from two supply reels while rotating one wire supply reel about the other. A capstan and tachometer measure the linear rate at which the twisted pair is being drawn. The output of the tachometer is controllably and variably divided and used to control a power inverter that drives a motor which rotates the one wire supply reel about the other. The variable ratio between the linear wire movement and the rotary or twisting movement is controlled by a random generator producing a series of numbers representing length per twist of the twisted pair, between fixed limits.
