Abstract:
1. An electronic circuit-integrated motor device comprising: a motor case formed in a tubular shape and having an end wall at one axial side thereof; a stator arranged radially inside the motor case and wound with coils of a plurality of phases; a rotor arranged radially inside the stator; a shaft fixed to the rotor to rotate therewith; and a semiconductor module including a switching element, a resin part and a coil terminal, the switching element being formed in a semiconductor chip for switching coil currents supplied to the coils, the resin part embedding the semiconductor chip therein and having a top wall surface and a bottom wall surface that faces the top wall surface and the end wall of the motor case in an axial direction of the motor case, and the coil terminal protruding from the resin part and having a connection part directly connected to the coil, wherein a distance between the connection part and the end wall of the motor case is greater than a distance between the bottom wall surface of the resin part and the end wall, in the axial direction of the motor case, and wherein the coil terminal is protruded from the bottom wall surface of the resin part.
