Electric drive unit

An electric drive unit, comprising:

• a multi-phase AC motor including a rotor, a stator, and a plurality of first terminals through which a current of each phase of multi-phase alternating current flows;
• a power converter including a plurality of second terminals associated with the plurality of first terminals;
• and
• an electric motor case that includes a wall portion formed to partition between the AC motor and the power converter, and is formed to house the AC motor, wherein
• the power converter is fixed to the electric motor case so as to partially overlap the AC motor in an axial direction of the rotor while interposing the wall portion between the power converter and the AC motor,
• each of the plurality of first terminals includes:
• a first extended portion extending from the stator along the axial direction;
• and a first fastening portion which is a tip of one of the plurality of first terminals,
• each of the plurality of second terminals includes:
• a second extended portion extending along an extending direction at a portion of the power converter that does not overlap the AC motor in the axial direction;
• and a second fastening portion which is a tip of one of the plurality of second terminals, the extending direction being a direction from the power converter toward an inside of the AC motor in a radial direction,
• the first fastening portion and the second fastening portion are fastened to each other via a fastener, and
• the electric motor case includes:
• a communication hole formed in the wall portion to pass the plurality of second terminals;
• and a service hole formed in a portion located on an extension line of the fastener parallel to an insertion direction of the fastener with respect to the first and second fastening portions.
