摘要： A brush holding apparatus is mounted to an inner wall surface of a rear bracket and a cap mounted to a head portion of a brush holder portion is exposed through an opening in the rear bracket. Brushes are housed inside brush insertion apertures of the brush holder portion and are placed in elastic contact with slip rings by springs. An abrasion detection terminal is insert molded into the brush holder portion, a contact thereof projecting inside one of the brush insertion apertures and coming into contact with the corresponding spring when the brushes are abraded by a predetermined amount.

摘要： A method of manufacture for a stator core including the steps of a) punching a stacked plurality of long bands of sheet steel to form strip laminations having tooth portions and core back portions; and b) spirally winding the strip laminations and integrating the wound strip laminations. The stacked plurality of long bands of sheet steel can be punched over their width such that at least one pair of the strip laminations is formed and two of the strip laminations form a pair by intermeshing the protrusions and recesses of their respective tooth portions.

摘要： An object of the present invention is to provide an automotive alternator achieving high output by overlapping a laminated core of a stator and yoke portion of a field rotor in an axial direction, and enabling electromagnetic noise to be reduced by prescribing dimensional relationships in the field rotor. In this automotive alternator, a ratio (R2/R1) between an outer radius R2 of a cylindrical portion of a Lundell-type core and an outer radius R1 of the Lundell-type core is set to a range from 0.50 to 0.54, and a ratio (Tr/Tp) between an axial overlap length Tr between the laminated core of the stator and the yoke portions of the Lundell-type core and an axial length Tp of the yoke portions is set to a range greater than or equal to 0.2.

摘要： An alternator includes a rear-end fan which is constructed so as to have greater capacity than a front-end fan. The construction is such that a flow rate in a front-end ventilation pathway in which a cooling air flow enters through front-end air intake apertures is deflected centrifugally by the front-end fan and is then expelled through front-end air discharge apertures is greater than a flow rate in a rear-end ventilation pathway in which a cooling air flow enters through rear-end air intake apertures is deflected centrifugally by the rear-end fan and is then expelled through rear-end air discharge apertures.
