摘要:
A rotary electric machine integrated with a control device includes stator current switching circuit sections, each of which has a switching element disposed on a heat sink; a field current switching circuit section; a control circuit section which controls the stator current switching circuit sections and the field current switching circuit section; and a case which contains the stator current switching circuit sections and has suction holes each for a cooling air inflow, the heat sinks of three phases for the stator current switching circuit sections being disposed in a circumferential direction of the rotary electric machine. In the rotary electric machine, of the suction holes of the case, an area of the suction hole for the heat sink of the phase disposed in the midst is set to be larger than an area of the suction hole of other phase.
