Controller-integrated electric rotating machine

A controller-integrated electric rotating machine comprising:

• a stator provided with a stator winding that generates AC electric power or that is supplied with AC electric power;
• a rotor provided with a rotor magnetic pole that is magnetically coupled with the stator winding;
• a bracket that is fixed on the stator and pivotably supports the rotor;
• a plurality of power modules that are connected between the stator winding and an external DC power source and are included in an electric-power conversion circuit that performs electric-power conversion between DC electric power and AC electric power;
• a heat sink on which the plurality of power modules are mounted and that refrigerates the power modules;
• a bus bar that is electrically connected with the DC power source;
• a power-input/output conductor that is fixed to the bus bar and is electrically connected with the DC power source and the bus bar;
• and
• a case, made of an insulator, that is fixed to the heat sink and is provided with a terminal that is electrically connected with the bus bar and the plurality of power modules, wherein the bus bar is provided with a single electric connection portion and at least one mechanical connection portion other than the electric connection portion, electrically connected with the terminal by means of the single electric connection portion, and mechanically connected with the heat sink through an insulating material by means of at least one mechanical connection portion.
