Abstract
A method for assembling a generator rotor carrying permanent magnets defining a magnetic field and a generator stator defining an armature having a plurality of coils includes moving one or both of the generator rotor and the generator stator towards the other of the generator stator and the generator rotor to generate relative movement between the generator rotor and the generator stator. Simultaneously with the relative movement, the coils of the armature are electrically feed such that circulating currents along the armature create a magnetic field in an opposite direction of the magnetic field created by the permanent magnets to reduce a magnetic attraction between the generator rotor and the generator stator.
