STATOR INSULATION FOR COLD MAGNETS |
| 摘要 |
A generator for a wind turbine, in particular a direct drive wind turbine is provided. The generator includes a rotor assembly that is rotatable around a rotary axis and a stationary stator assembly, wherein the rotor assembly and the stator assembly are arranged with respect to each other such that a gap exists between the rotor assembly and the stator assembly, so that the rotor assembly is rotatable with respect to the stator assembly. The stator assembly has a surface facing the gap and the rotor assembly. The stator assembly includes a thermal insulation layer applied onto the surface for reducing an exchange of thermal energy between the rotor assembly and the stator assembly. |
