Rotating electric machine

摘要

A rotating electric machine (1) includes a cooling frame (17) disposed on the outer circumference side of a housing (11) and making a first liquid coolant (101) circulate therethrough to cool the inside of the rotating electric machine (1). The cooling frame (17) includes a flow passage (21) through which the first liquid coolant (101) circulates, a flow inlet (19) connected to one end of the flow passage (21) so as to make the first liquid coolant (101) flow from the outside into the flow passage (21), and a flow outlet (20) connected to the other end of the flow passage (21) so as to make the first liquid coolant (101) having flown through the flow passage (21) flow to the outside. The rotating electric machine (1) is configured that, when the flow passage (21) is divided into a front half portion (22) closer to the flow inlet (19) and a latter half portion (23) closer to the flow outlet (20), the front half portion (22) becomes a portion where the first liquid coolant (101) mainly cools the second liquid coolant (100), and the latter half portion (23) becomes a portion where the first liquid coolant (101) mainly cools the gas coolant (102).
