| 摘要 |
The invention concerns electric rotating machines whose rotor inductor operates at a very low temperature, characterized in that the rotor of these machines comprises a bearer cylinder made of a non-magnetic material inside which a closed cylindrical body for supporting the inductor winding is fixed in a fluid-tight manner so as to form, between the bearer cylinder and the closed cylindrical body, a space subjected to a thorough vacuum. The invention applies more particularly to electric generators with an inductor cooled by liquid helium.
