发明名称 ROTATING ELECTRIC MACHINE
摘要 <P>PROBLEM TO BE SOLVED: To provide a rotating electric machine that suppresses the dispersion of dust including particles and is achieved in downsizing by a simple constitution. <P>SOLUTION: In an AC servo-motor M that is one embodiment of the rotating electric machine, there are formed a suction port 10a that communicates with a space A formed between a bearing 7b at a load opposite side and an armature in a housing 5, an exhaust port 10b that communicates with a space B formed inside a bearing 7a at a load side in the housing 5, and an exhaust port 10c that communicates with a space C formed at a place where a rotating shaft 8 penetrates a hole of a bracket 6a outside the bearing 7a at the load side. A flow of air or the like flowing toward the exhaust port 10b and the exhaust port 10c from the suction port 10a is formed, and the dust generated by grease applied to the bearings 7a, 7b is led to a place apart from the AC servo-motor M from the exhaust port 10b and the exhaust port 10c via a pipe or the like. <P>COPYRIGHT: (C)2007,JPO&INPIT
