IPC: H02K1/27
Filed: 2018-11-08
Abstract: To provide a rotary machine rotor that suppresses thermal demagnetization of a permanent magnet.SOLUTION: In a rotor 10 of an IPM motor 1, since a second heat conduction layer 42 having a low heat conductivity is located on the stator 20 side (that is, the second surface 30b side) of the permanent magnet 30, the second heat conduction layer 42 prevents heat from transferring from the rotor core 14 to the permanent magnet 30. Further, since a first heat conductive layer 41 having high thermal conductivity is located on the shaft 12 side (that is, the first surface 30a side) of the permanent magnet 30, the heat transferred from the rotor core 14 to the permanent magnet 30 is radiated from the shaft 12 side of the permanent magnet 30.
