    摘要： The invention provides an improvement in a slip ring (20) adapted to provide electrical contact between a stator (21) and a rotor (22). The improvement includes: a current-carrying conductor (23) mounted on the stator; a brush tube (24) mounted on the conductor; a fiber bundle composed of a number of individual fibers (26), the upper marginal end portions of the fibers being received in said brush tube, a portion of the brush tube being crimped or swaged to hold the upper marginal end portions of said fibers therein, the lower ends of the fibers in the bundle extending beyond said brush tube and being adapted to engage said rotor; a collimator tube (25) surrounding a portion of the brush tube and extending therebeyond, the lower end of the collimator tube being adapted to limit lateral movement of the lower marginal end portions of said fibers in said bundle when the rotor rotates relative to said stator; and a fluid reservoir mounted on the collimator tube (28). The fluid may be an lubricant, a corrosion inhibitor, a fluid having a high dielectric strength additive to prevent arcing, or some other fluid.

    摘要： A slip ring has a slip ring track with a contact area, the contact area containing a plurality of pores or cavities. A lubricant is held within these pores and cavities and is enclosed by a top coating. When a slip ring brush is sliding over the slip ring track, it rubs off particles of the top coating, therefore opening some of the pores or cavities which release parts of the lubricant contained therein. This lubricant reduces surface friction of the slip ring brush at the slip ring track and therefore further wear, which results in an extended lifetime.

    摘要： A miniature motor has a tubular case (1) closed at one end and a permanent magnet (2) fitted to the inner surface thereof. A case cap (6) closes the open end of the case, and a rotor (5) with an armature (3) and a commutator (4) is rotatably supported by bearings (9,10) provided on each end of the case (1). Brushes for making sliding contact with the commutator (4) are supported on the case cap (6). The atmosphere enclosed within the motor comprises a polymer having a molecular weight of 250 to 5000.
