ROTATING MACHINE
A magnet-embedded rotating machine includes a rotor including first and second magnets, and a stator. The first magnet is radially spaced from a facing surface of the stator by a first distance or longer, and the second magnet is radially spaced from the facing surface of the stator by a second dist...

Zusammenfassung: | A magnet-embedded rotating machine includes a rotor including first and second magnets, and a stator. The first magnet is radially spaced from a facing surface of the stator by a first distance or longer, and the second magnet is radially spaced from the facing surface of the stator by a second distance or longer, the second distance being longer than the first distance. Hco(A) > Hco(B), Hci(A) > Hci(B), Hco(A) > Hci(A), and {Hco(A)/Hci(A)} > {Hco(B)/Hci(B)}. Hco(A) represents a coercive force of the first magnet within a first temperature range corresponding to startup temperatures of the rotating machine. Hco(B) represents a coercive force of the first magnet within a second temperature range corresponding to steady state driving temperatures of the rotating machine. Hci(A) represents a coercive force of the second magnet within the first temperature range. Hci(B) represents a coercive force of the second magnet within the second temperature range. |
