摘要： A centrifugal compressor for compressing gas has a casing, a rotary shaft, an impeller, a diffuser, a first scroll, a second scroll, a first passage, a second passage, and a switching member. The rotary shaft is supported by the casing. The impeller is rotatably fixed to the rotary shaft, and sends the gas radially outward to a flow path downstream thereof. The diffuser is formed around the impeller. The first scroll is formed around the diffuser. The second scroll is formed between the diffuser and the impeller. The first passage is formed from the impeller to the first scroll through the diffuser. The second passage is formed from the impeller to the second scroll. The switching member switches the flow path between the first passage and the second passage by opening and closing the diffuser.

摘要： A centrifugal compressor has a housing assembly and an impeller rotatably connected to the housing assembly. Gas introduced into the housing assembly by rotation of the impeller is compressed at least by centrifugal force. One aspect of the present invention is that the impeller includes an inducer portion having a pressure surface and a suction surface and a hole extending between the pressure surface and the suction surface. Another aspect of the present invention is that the centrifugal compressor includes a diffuser located downstream of the impeller, a volute in communication with an outlet of the diffuser, and a reflux passage connecting the diffuser with the volute for returning part of gas in the volute to the diffuser.

摘要： An accommodating recess (21A, 21B) has a magnet accommodating portion (19A, 19B) for accommodating a permanent magnet (17A, 17B) and a cavity (20A, 20B), which is located at the q-axis side of the magnet accommodating portion. The cavity opens through a rotor outer circumferential surface (162). A starting point (Pa1, Pb1) of an outer cavity forming surface (201A, 201B) is located on the rotor outer circumferential surface. The outer cavity forming surface intersects either a magnetic pole surface or an imaginary extended plane (23A, 23B) of a magnetic pole facing surface (191A, 191B). The rotor outer circumferential surface (162) includes portions of an imaginary annular line (E). A starting point (Pa1, Pb1) of the outer cavity forming surface (201A, 201B) is located between the d-axis and an intersection point (Qa, Qb) between the imaginary annular line and the imaginary extended plan of the magnetic pole facing surface.

摘要： An interior permanent magnet motor includes a rotor and a stator. The rotor includes a rotor core. The rotor core is formed by laminating steel plates each including pairs of magnet insertion holes and pairs of cutouts. Each pair of magnet insertion holes includes two magnet insertion holes that are arranged in a V-shape, the wide end of which is relatively closer to the outer edge with a support portion located in between. Each pair of cutouts is formed at q-axis ends of the corresponding magnet insertion holes, and includes two cutouts connected to the outer edge of the rotor core. In a state where the permanent magnets are inserted in the magnet insertion holes, a gap is formed at a d-axis end of each magnet insertion hole.
