摘要:
An electronic circuit including semiconductor modules and capacitors is positioned in the axial direction of a motor. Each semiconductor module is longitudinally positioned in contact with a heat sink. More specifically, a line perpendicular to the surface of a semiconductor chip included in the semiconductor module is perpendicular to the axis line of the motor. Consequently, each capacitor is positioned so that at least a part of the positional range of the capacitor in the axial direction of the motor coincides with the positional ranges of the semiconductor module and the heat sink in the axial direction.
