<P>PROBLEM TO BE SOLVED: To return a coolant, which is supplied from an area above a coil end and passes the coil end to be dropped, to the coil end again in a rotary electric machine which is installed with a rotation shaft horizontally arranged. <P>SOLUTION: A coolant, which is supplied from a coolant supply port 26 and passes a coil end 22 to be dropped, is received by a coolant receiving member 28. The coolant receiving member 28 is disposed extending along a part of an inner peripheral surface of an upper portion 22a of the coil end. The received coolant flows along the coolant receiving member 28 and flows out from both ends to be poured again into the coil end 22. In order to increase the flow rate of the coolant when the coolant is flowed out, a passage cross section area of the coolant receiving member 28 is set so as to be large at a top part and be small at an end part. <P>COPYRIGHT: (C)2013,JPO&INPIT |
