Abstract
A method for in-situ magnetization of a generator rotor is provided. The generator has a stator and the rotor is located inside the stator. An air gap is formed between an outer radial portion of the rotor and an inner radial portion of the stator. The rotor has a plurality of excitation windings and a plurality of permanent magnets. The method includes the step of applying a current to the excitation windings, and the current is greater than a normal excitation current. A maintaining step maintains the current for a time period sufficient to magnetize the permanent magnets. The magnetization of the permanent magnets occurs on the rotor in-situ and while the rotor is inside the stator.
