摘要： A rear-end bearing accommodating portion that has a floored cylindrical shape is formed integrally on a rear bracket. A brush apparatus is mounted to the rear bracket by mounting a slinger portion onto an end portion of a shaft so as to cover slip rings. A rectifier is mounted to the rear bracket in close proximity to the rear-end bearing accommodating portion and the slinger portion. A rolling bearing is configured into a creep preventing bearing in which a resin band is mounted into a ring-shaped recessed groove that is recessed into an outer circumferential surface of an outer ring. A first slit is disposed through the slinger portion so as to be positioned so as to face downward when mounted to a vehicle and so as to communicate between an internal portion and an external portion of the slinger portion.

摘要： An alternator (AC generator) to be mounted on a vehicle comprises slip rings, brushes, a brush holder, a rear cover, and sealing members. The slip rings are fixed on a rotary shaft and rotatable together with the rotary shaft. The brushes are slidable on the slip rings and the brush holder accommodates the brushes therein. The slip-ring cover covers the slip rings as well as the brush holder and the rear cover covers electronic components including the brushes. The sealing members give a sealing performance to an inner space containing slid portions of the brushes on the slip rings. The rear cover, the brush holder, and the sealing member have a ventilating passage for positively causing an flow of air from the inner space containing the slid portions of the brushes on the slip rings to an outside of the alternator.

摘要： An automotive alternator according to the present invention includes a rotary shaft, slip rings, a brush holder, brushes, a cover, a seal member, a cooling air flow path, and a water shield. The slip rings are fixed to an end portion of the rotary shaft. The brushes are accommodated in the brush holder and so held by the brush holder as to establish sliding contacts with the slip rings to excite the automotive alternator. The cover covers the end portion of the rotary shaft, the slip rings, the brush holder, and the brushes. The seal member is interposed between the brush holder and the cover. The cooling air flow path is formed between the seal member and one of the brush holder and the cover to supply cooling air to the brushes. The water shield works to prevent water from entering into an entrance of the cooling air flow path.

摘要： A fan 30 for mounting at one end of the armature of an electric motor comprises a ring portion 40 of moulded thermoplastic material supporting an annular plate 42 with integrally formed fan blades 46 in axial alignment with exhaust vents formed in the housing of the motor. The fan blades 46 extend radially across a face of the annular plate 42 remote from the ring portion 40 and extend into the annulus of the plate. The blades 46 are grouped and centered on the winding tunnels of the armature with the axially outer edges of the blades of each group joined together by a radial wall 50 within the radial spacing of the annulus of the plate 42 but axially spaced therefrom.

摘要： A novel homopolar machine, i.e. a device comprising at least one electrically conductive rotatable rotor configured to flow a current in a current path and a magnetic field source configured to apply a magnetic field penetrating the rotor and intersecting the current path when the rotor rotates, including the following inventive aspects: The source of magnetization is one or more bar-type magnet(s) whose geometric and magnetic axes are parallel and normal to the rotation axis, respectively, so that the magnetic field penetrates the rotor in two separate zones with its direction pointing away from the axis in one zone and towards it in the other. The current path runs along one of the zones and returns in the other, causing a Lorenz force that acts in the same rotational sense in both zones. The current path is constrained by means of current channeling means in the rotor.
