Abstract: A slip ring for use in a slip ring brush type rotation sensor device, includes a metal ring having an approximately cylindrical shape, and a resin ring that supports the metal ring. Slits extending in an axial direction are formed in respective side surfaces on outer peripheries of the metal and resin rings. The metal ring includes a common part formed on a side surface at one end along the axial direction of the approximately cylindrical shape and segmented by the slits into segments to form common regions, so that adjacent common regions are electrically connectable to each other, and a detection part formed on a side surface at the other end and segmented by the slits into segments to form conducting regions and isolated regions that are alternately provided with the slit interposed between adjacent conducting and isolated regions.

Abstract: A magnetic propulsion drive system provides power output by including the use of permanent magnets repelled by electromagnets on adjacent rotor assemblies. In some embodiments, the electromagnets may be inactive until synchronized to face an opposing permanent magnet of the same polarity. The electromagnet may be energized thus causing a repellant force with the permanent magnet causing radial momentum in the rotor assembly to rotate a larger drive module of rotor assemblies. Embodiments may include two or more drive modules arranged to position opposing magnets of the same type so that each drive modules is driven producing and output torque through a drive shaft. Some embodiments include a stator element which may be a cage surrounding the rotor assemblies. Interaction of the magnets with the stator simultaneously provides electric field generation and current while producing mechanical drive output.

Abstract: A slip ring unit for an electrically excited rotor of a rotary dynamo-electric machine includes an electrical terminal which protrudes axially from an end face of the slip ring unit and having a contact point and a circumferential slip contact surface electrically connected to the electrical terminal. Disposed adjacent to the slip contact surface is an insulation element, with end plates axially retaining the circumferential slip contact surface and the insulation element. An electrically insulated support element is arranged on an end face of the slip ring unit and has a cross section which substantially matches a cross section of the slip ring unit. The support element axially surrounds the electrical terminal and radially supports the electrical terminal.
