摘要： A brush holder assembly for use in an electrical generator having a moving conductive surface may include a brush holder, such as a brush box, that is configured to be removably mounted to a mounting element on the electrical generator. A carbon brush may be slidingly disposed with the brush holder and may be biased into sliding contact with the moving conductive surface. The brush holder assembly includes a handle that is moveable between an unlocked position in which the brush holder is removable from the mounting element and a locked position in which the brush holder is secured relative to the mounting element. A circuit board is disposed within the handle and includes a sensor that provides an indication of an occurrence of an anomalous and/or threshold condition of the carbon brush.

摘要： A current collector and a conductor line system having such a current collector. The current collector has a holder and a carbon brush arranged in carbon brush support movable relative to holder in a feed direction from and to the conductor line. The carbon brush is movable in a feed direction from and to conductor line. A better and reliable guiding of the carbon brush on the conductor line and simpler design of the current collector, uses a current collector in which the carbon brush is additionally movable in a transverse direction running essentially across the longitudinal direction, a spring element being provided between the carbon brush and holder.

摘要： A shunt extends from a brush received by a brush box of a brush holder. The first end of the shunt can be connected to the brush, and the second end of the shunt can connect to the brush holder. A lever connects to a back plate of the brush holder, and the lever may reversibly and selectively rotate between a first position and a second position; the lever can have a distal portion, and the second position of the lever secures a portion of the shunt between the distal portion of the lever and another component of the brush holder. The secured portion of the shunt can restrict downward movement of the brush in the brush box, while a spring pushes downward on the brush in the brush in the brush box, to thereby fixedly position the brush in the brush box.

摘要： This motor includes a yoke, an armature, a brush holder and a ground member. The yoke has the shape of a bottomed cylinder that has an inner surface to which a magnet is affixed. The armature is contained within the yoke. The brush holder is arranged in an opening of the yoke, and holds a feed brush for supplying an electric current to the armature, and a bearing that axially supports a rotary shaft of the armature. The ground member is in contact with the bearing and the yoke. The ground member is affixed to a ground terminal that is held by the brush holder.
