Title:
ROTATING MACHINE
Document Type and Number:
WIPO Patent Application WO/2023/132201
Kind Code:
A1
Abstract:
According to the present invention, it is possible to cool electric components more efficiently than conventional products. A motor comprising: a rotating machine housing that houses a rotor and a stator; an electric component housing 113 that houses a switching unit serving as a high-speed semiconductor unit, and that is adjacent to the rotating machine housing on the other side, out of one side and the other side in the axial direction (arrow A-B direction) parallel to the rotational axis of the rotor 2; an electric component cover that closes, at an end on the other side in the axial direction of the electric component housing 113, an opening oriented to the other side; and an electric-component refrigerant flow path through which a refrigerant for cooling the switching unit in the electrical equipment housing 113 flows, and at least a portion of which in the refrigerant flowing direction is disposed within the electric component housing 113. The motor is characterized in that: a semiconductor module 164 of the switching unit constitutes at least a wall of said portion; and at least in said portion in the electric-component refrigerant flow path, the refrigerant in the inside comes directly into contact with the semiconductor module 164.
