摘要： A brushed rotatory device (10) includes a stator, a rotor (14), an impeller (70), and a chamber (48) accommodating the commutator (16) and brushes (52) to contain debris from consumed brushes. The impeller causes air flow to dissipate heat generated by the rotatory device and may further carry the consumed brush debris away. The rotatory device includes flow channel(s) (72) which communicates with the impeller exhaust and accommodates absorbent or filtering materials (88) to trap the debris in the air flow. The commutation area may be double contained by using flange(s) (202) or wall(s) (42) to trap or confine a greater part of the debris in a localized region or to reduce noise from the rotatory device operations.

摘要： A rotary electric machine includes a rotating shaft 18 rotatably supported by a housing, a stator including armature windings, a rotor including field cores and field windings, slip rings electrically connected to the field windings, brushes contacted and electrically connected to the slip rings, and a brush holder including the brushes and terminals. The rotor is provided with one or more fans. The terminals include exposed portions exposed at least partially from the brush holder, and the exposed portion are disposed on a ventilation path of a cooling airflow W generated by rotation of the fans. Accordingly, since the exposed portion are disposed on the ventilation path of the cooling airflow, heat caused by an energization can be efficiently dissipated, and heat generated in the brushes due to the interfacial friction is dissipated from the exposed portions.

摘要： A motor includes a substantially cylindrical housing, a rotor assembly, a cover, a sleeve, and a cooling fan. The cooling fan is installed at one end of a rotating shaft of the rotor assembly to induce airflow. The sleeve, being closely fitted around the housing, is integrally formed with a plurality of wind-caching projections, each of which is located above one upstream through hole defined on the housing and faces towards the cooling fan. The wind-catching projections can receive the airflow induced by the cooling fan and guides the airflow to enter the housing via the upstream through holes to dissipate the heat accumulated in the motor, so that the motor can be prevented from damages due to heat accumulation. Therefore, the performance and service life of the motor can be increased.
摘要翻译：马达包括基本上圆柱形的壳体，转子组件，盖子，套筒和冷却风扇。冷却风扇安装在转子组件的旋转轴的一端以引起气流。紧密配合在壳体周围的套筒整体地形成有多个风速缓冲突起，每个风挡高度缓冲突起位于限定在壳体上的一个上游通孔上方并朝向冷却风扇。吸风突起可以接收由冷却风扇引起的气流，并引导气流经由上游通孔进入壳体，以散发积聚在电动机中的热量，从而可以防止电机由于热积聚而损坏。因此，可以提高电机的性能和使用寿命。
