制御装置一体型回転電機
Document Type and Number:
Japanese Patent JP4851575
Kind Code:
B2
Abstract:
There is obtained a controller-integrated electric rotating machine that is superior in terms of a cooling effect. In a controller-integrated electric rotating machine provided with a stator 3 configured with an iron core 3B and a stator winding 3A, a rotor 4 having a cooling fan 5, an inverter power circuit 20 that is a control apparatus for applying a stator current to the stator winding 3A, and a bus bar 30 that supplies the inverter power circuit 20 with electric power from a battery, the inverter power circuit 20 includes a power module 21 that has a function of switching the stator current, a heat sink 23 on which the power module 21 is mounted by the intermediary of an insulating layer, and an insulator case 25 that incorporates the power module 21 and holds respective terminals of the power module 21; and the bus bar 30 is connected with terminals 22a, 22b, 22c, and 22d of the inverter power circuit 20 and has a cooling fin 30a.
