Abstract:
This centrifugal compressor is provided with a rotational shaft, a motor, an impeller, a housing, a shaft path extending in an axial direction inside the rotational shaft, and a radial path extending in a radial direction from the shaft path. The housing has an impeller room, a motor room, and a suction port. The motor has a stator and a rotor. The stator has a stator core and a coil end that is a part of a coil wound on the stator core. The coil end protrudes from an end surface of the stator core. The shaft path opens toward the suction port. The radial path is in communication with the motor room. The rotational shaft has a protrusion part protruding toward the coil end. The protrusion part includes a part of the radial path. Air sucked into the shaft path from the suction port flows to the coil end via the radial path.
