Abstract:
1. An electronic circuit-integrated motor device comprising: a tubular motor case; a stator positioned on a radially inside part of the motor case and wound with a multiple-phase coil; a rotor positioned in a radially inside part of the stator; a shaft fit in the rotor to be rotatable the rotor; a plurality of semiconductor modules, each having a switching element for changing a coil current flowing to the multiple-phase coil; and a linking member linking the plurality of semiconductor modules to form a linked semiconductor module unit, wherein each of the semiconductor modules includes at least one semiconductor chip that forms the switching element, a land on which the semiconductor chip is mounted, and a resin part that encapsulates the semiconductor chip and embeds the land therein, wherein the linking member is comprised of embedded portions, each respectively embedded in a resin part, and exposed portions that extend between two embedded portions and are exposed from the resin parts, said embedded portions and said exposed portions being formed integrally and continuously in one piece, wherein the linking member includes a bent portion that is bent at the exposed portion, and further comprising a heat sink mounted on an axial end wall of the motor case in a raised manner, wherein the linked semiconductor module unit is bent at the bent portion on a radially outside part of the heat sink along the heat sink, and positioned around a rotation axis of the motor, and wherein the plurality of semiconductor modules are mounted outside the heat sink.
