  • Automotive alternator having flexible bearing cover
    Patent number: 7589448
    Abstract: According to the present invention, there is provided an automotive alternator which includes a rotor, a stator, a rolling bearing, and a bearing cover. The rotor includes a rotary shaft and works to create a rotating magnetic filed. The stator works to generate an AC power in the rotating magnetic field created by the rotor. The rolling bearing rotatably supports the rotary shaft of the rotor. The bearing cover covers an axial end of the rolling bearing. The bearing cover has flexibility in an axial direction of the rotary shaft and is fitted in place with the flexibility thereof.

  • Rotary electric machine
    Patent number: 6664699
    Abstract: A rotary electric machine has a brush assembly that defines a slip ring cavity enclosing slip rings and brushes. The brush assembly provides two different outlets for particles and cooling air. The first outlet is located on a side with respect to a shaft and is directed in an axial backward direction. The second outlet is located on a bottom and is directed in a radial downward direction. The second outlet is close to a fan for inducing airflow in the slip ring cavity.
