    • An alternator for use in an automobile comprises a first frame, a second frame, a stator, a shaft, a rotor, a current supply system and fans. The shaft is rotatably coupled to the first frame and the second frame, and extends outwardly beyond the first frame. The current supply system has a pair of slip rings, a pair of brushes and a brush holder. The slip rings are fixed to the shaft, and are electrically connected to a coil of the rotor. The brushes are urged against and in slidable contact with the slip rings, respectively. The brush holder is fixed to the first frame for retaining the brushes; and has a slip ring shield portion for covering and protecting the slip rings. The slip ring shield portion has openings which allow dust produced by the wearing of the brushes to be blown by the action of fans.
    • 用于汽车的交流发电机包括第一框架,第二框架,定子,轴,转子,电流供应系统和风扇。 轴可旋转地联接到第一框架和第二框架,并且向外延伸超过第一框架。 目前的供应系统有一对滑环,一对刷子和一个刷架。 滑环固定在轴上,并与转子的线圈电连接。 刷子分别被推压并与滑环滑动接触。 电刷架固定在第一框架上以保持刷子; 并具有用于覆盖和保护滑环的滑环屏蔽部分。 滑环防护部具有能够通过风扇的作用而使刷子磨损而产生的粉尘的开口。
