Abstract:
1. A controller-integrated electric rotating machine comprising: an electric rotating machine having a rotor with a rotating shaft, a stator disposed so as to surround the rotor, and a brush holder with brushes; a power circuit unit having switching elements for converting DC power to AC power for supplying the AC power to the electric rotating machine; a control circuit unit for controlling the switching elements of the power circuit unit; and a rotational position detection sensor arranged on the rotating shaft for detecting the rotation of the rotating shaft, wherein the control circuit unit is disposed at a position where the power circuit unit is not disposed when viewed in the direction of the rotating shaft, and is disposed at a position shifted radially outward so as not to be overlapped with the rotational position detection sensor when viewed in the direction of the rotating shaft, wherein the switching elements are arranged in a substantially U-shape, wherein the brush holder is arranged in the periphery of the switching elements and is arranged not to overlap with the switching elements when viewed in a direction perpendicular to the rotating shaft, wherein the control circuit unit comprises a control circuit board and at least a portion of the control circuit board extends to an outside of a cover of the electric rotating machine; and wherein the rotational position detection sensor is disposed on the rotating shaft and is located relatively rear side from the brush holder.
