摘要： An electric power tool includes a housing, a commutator motor housed in the housing, and a brush holder disposed in the housing. A fan is disposed to the commutator motor. The brush holder includes a metal sleeve and a resin base. The metal sleeve houses a brush, and the resin base holds the metal sleeve at one surface side of the resin base. The resin base includes an opening portion exposing the metal sleeve to the opposite side surface of the one surface side. The brush holder is disposed in a direction that the resin base is disposed at the fan side such that rotation of the fan causes air suctioned from an air intake opening disposed in the housing at the metal sleeve side to be discharged from an exhaust outlet disposed in the housing at the fan side after passing through the brush holder and a commutator.

摘要： An alternative energy generating apparatus is provided. The apparatus comprises a stationary metal coil or coils positioned by, above, below, or beside a magnet or a rotor of magnets with one or more imbedded magnets (e.g., rare earth magnets). Magnets may be imbedded along an outer part of a disc-like rotor. The one or more coils may be held in a coil plate apparatus, essentially parallel to the magnet rotor. The provided apparatus further comprises a shaft having a gear ratio for turning the rotor of magnets, such as by hand or by a motor in order to achieve a high turning velocity. The magnets generate an electromagnetic field, which when rotated against the stationary metal coils, produce an electric current.

摘要： The current invention is regarding a slip ring for transmitting high speed electrical signal across a rotating interface, especially for transmitting Ethernet data. It consists of sandwich assembly with multiple conducting plates individually sandwiched by multiple insulating spacers and a brush block assembly with multiple conducting brushes. The input Ethernet cable is attached on said sandwich assembly and the wires from input cable can be individually soldered into the central hole of each conducting plate (The wires are always off-centered in prior art). The output Ethernet cable is soldered on said brush block. Said brush block assembly and said sandwich assembly are rotatable relative to each other through bearings to form a rotational interface. As a result, high speed electrical signal can be transmitted across the rotating interface without suffering from phase shift and data distortion as in prior arts due to unequal path lengths.

摘要： A brush direct current motor has a stator with a plurality of coils that correspond to a number of stator windings, a rotor with a number of poles, and a commutator. The commutator is connected to a first terminal of a direct current power source to convert the power into N phase alternating current. One end of each stator winding is connected to a respective phase of the alternating current via a brush and the other ends of the stator windings are connected to the second terminal of the direct current power source.
