Definitions

  • an iron core member is disposed between the hollow portions 11 to 14 per pole of the rotor core 9. That is, the first core member is disposed between the first cavity portion 11 and the second cavity portion 12, the second core member is disposed between the second cavity portion 12 and the third cavity portion 13, and the third A third core member is disposed between the cavity 13 and the fourth cavity 14.
  • the weight of such an iron core member becomes heavier as the iron core member located on the radially inner side. That is, the weight of the second core member is larger than the weight of the first core member, and the weight of the third core member is larger than the weight of the second core member.
