<P>PROBLEM TO BE SOLVED: To provide a rotating electric machine device that is an integration of a rotating electric machine and a driving circuit thereof, in which structure of the driving circuit is simplified and detachability of the driving circuit is improved. <P>SOLUTION: A rotating electric machine device comprises: a rotating electric machine 1; a driving circuit 2 for supplying electric power to the rotating electric machine 1 by converting DC power to AC power with a switching element 51 connected between a high tension side DC bas 3 and a low tension side DC bus 4; and a liquid-cooled heat sink 8 having a first surface on which the rotating electric machine 1 is disposed and a second surface opposite to the first surface, on which the switching element 51 of the driving circuit 2 is disposed. The high tension side DC bas 3 and the low tension side DC bus 4 are arranged to be insulated from each other via an insulator, forming a DC bus unit 90 by being laminated in layers. The DC bus unit 90 is disposed so as to face the second surface of the liquid-cooled heat sink 8, and the DC bus unit 90 is connected to a DC bus power supply line from a DC power source on the surface opposite to the surface where the DC bus unit 90 faces the liquid-cooled heat sink 8. <P>COPYRIGHT: (C)2013,JPO&INPIT |
