Title:
DYNAMO-ELECTRIC MACHINE UNIT
Document Type and Number:
WIPO Patent Application WO/2023/145419
Kind Code:
A1
Abstract:
A dynamo-electric machine unit according to the present disclosure comprises: a dynamo-electric machine having a stator, and a rotor for rotating about the axis thereof relative to the stator; and an electric power conversion device located side-by-side with the dynamo-electric machine in the axial direction along the axis of the rotor. The electric power conversion device has a capacitor unit located in a central portion of the electric power conversion device, and a plurality of power modules arranged in the circumferential direction around the axis of the rotor so as to surround the capacitor unit. The capacitor unit has a capacitor body portion, a positive pole conductor, and a negative pole conductor. Each of the plurality of power modules has a power module body portion, a positive pole terminal connected to the positive pole conductor, and a negative terminal connected to the negative pole conductor. The positive pole terminals and the negative pole terminals are arranged so as to face the capacitor unit, and first connection portions of the positive pole conductor and the positive pole terminals, and second connection portions of the negative pole conductor and the negative pole terminals, are positioned between the capacitor body portion and the power module body portions.
