Method for establishing a wind turbine generator with one or more permanent magnet (pm) rotors, wind turbine nacelle and wind turbine

摘要

The invention relates to a method for establishing a wind turbine generator with one or more Permanent Magnet (PM) rotors. The method comprises the steps of:
manufacturing a generator prepared for taking one or more PM rotors,
manufacturing one or more rotors comprising a plurality of holding means prepared for retaining PM material,
mounting substantially non-magnetized PM material prepared for magnetization in said holding means before or after said one or more rotors are mounted in said generator,
connecting a magnetization system for magnetizing said PM material in the generator, and
magnetizing said PM material with said magnetization system. The invention also relates to a wind turbine nacelle, a wind turbine comprising said wind turbine nacelle and use of a wind turbine.
