摘要： A DC motor is provided that can suppress a commutator from wearing. A DC motor including a commutator formed of copper or a copper alloy of 99% or more copper, and a brush pressed against and in contact with the commutator, wherein the brush is composed of a sintered compact including graphite and copper powder, hard compound particles higher in hardness than any of the copper or the copper alloy and the graphite or the copper powder are contained in at least one of the commutator and the brush and are scattered on or near a contact surface of the commutator with the brush at least during use.

摘要： An electrical rotating machine, such as a generator or motor, communicates power from a stationary location to the rotating rotor of the rotating machine via opposed pairs of capacitor plates, one plate of each pair rotating with the rotor and one plate of each pair fixed not to rotate. Larger plate gaps suitable for mechanically rigid plates are possible through high-voltage and high-frequency AC signals managed by using a dielectric support design for the capacitor plates minimizing dielectric loss and/or impedance matching on the rotor.

摘要： A device to inhibit entanglement of catheter cables comprises a slip ring or a combined slip ring and fluid rotary joint. The device can include a servomechanism configured to power rotation of at least one of the slip ring and the fluid rotary joint. A detangling device for a cable plug configured to connect to a catheter handle comprises an outer cylinder configured to rotate relative to an inner cylinder while electrical connections between the inner and outer cylinders remain intact. A free rotary irrigation channel for a catheter handle inhibits entanglement of irrigation tubing.

摘要： A wire brush for a slipring includes a contact section, from which a stabilizer arm is extending backwards towards the brush block of the slipring. The stabilizer arm holds a friction section, which is in friction contact with the contact section at a friction contact area. Such contact, in operation, generates internal friction within the brush when the brush is moved and, therefore, suppresses oscillations of the brush.

摘要： A windscreen wiper motor with a housing is disclosed. In the housing, an armature shaft is arranged with a commutator which cooperates with carbon elements arranged in the region of a carbon holder plate, which elements are connected in an electrically conducting manner with voltage supply lines via electrical connections, preferably in the form of carbon strands. The voltage supply lines are connected with the electrical connections via a suppression device arranged at least substantially in a suppression housing, which is connected with the carbon holder plate, and the voltage supply lines are connected with at least one plug connection element, which is able to be connected to a plug connection region of the housing with mating plug connectors on the vehicle side.
