摘要： The longevity of electric contact brushes for dynamoelectric machines is extended by impregnating them with a material of octadecylamine with a hydrohalogen radical which is formed into a saturated solution in a hydrocarbon solvent. The saturated solution is applied to the brush either by direct application or by vacuum impregnation. The compound of octadecylamine with a hydrohalogen radical may also be introduced to the interface of the contact brush and commutator by means of a feeder brush. The carbon contact brush or feeder brush may be dipped in acid and washed in water prior to impregnation with the compound. Additionally, the compound may be mixed in a lacquer solution and painted on the leading edge of the contact brush or feeder brush.

摘要： The invention relates to a ground terminal and to a method for discharging electric currents from a rotor part of a vehicle (such as a rail vehicle or the like, that has an axle) to a stationary stator part of the vehicle. The ground terminal includes a retaining device and a terminal element. The retaining device is connected to the stationary stator part of the vehicle in electrically-conductive manner, the terminal element is disposed on and connected to the retaining in electrically-conductive manner. The terminal element is made mostly of graphite and subjected to a contact force by means of a spring device of the retaining device to realize an electrically-conductive sliding contact between a sliding contact surface of the terminal element provided for realizing the sliding contact and a terminal surface of the rotor part. The terminal element has an arc-shaped cross-section at least in portions thereof, an outer surface of the cross-section forming the sliding contact surface at least in sections. The sliding contact surface abuts radially against the terminal surface of the rotor part.

摘要： A carbonaceous material is fabricated by kneading of carbon powder and a binder. The carbonaceous material is granulated such that an average particle diameter of the carbonaceous material is 0.3 mm or more. A brush material is fabricated by mixing of the granulated carbonaceous material and metallic powder. A ratio of the metallic powder to a total weight of the brush material is adjusted to 1% by weight or more and 30% by weight or less. Pressure molding is performed on the fabricated brush material, and thermal processing is further performed on the brush material at a temperature at which a resin in the brush material is not carbonized.

摘要： A slipring brush includes a body of a metal wire or metal band having a contact area for contacting a slipring module. The contact area is selectively coated by a contact material like gold or silver or an alloy thereof. The body preferably includes Copper, Nickel, Iron, or an alloy thereof. Coating may be done by electroplating, physical vapor deposition (PVD) or chemical vapor deposition (CVD).

摘要： An oil lubricated compressor having a universal motor, efficient starting and re-starting characteristics, and a long operating life. The oil lubricated compressor can have a brushed or brushless universal motor which can drive a cooling fan and a pump. The universal motor can achieve a high torque to voltage ratio, as well as a high torque to current ratio, upon starting or re-starting of the compressor. Optionally, the oil lubricated compressor can use a single cooling fan disposed in the compressor at a location which is between the universal motor and a cylinder head of the pump.
