Abstract

It comprises a rotor and a stator that they both may be formed of a single piece or they may be formed of a number of sectors. The generator further comprises at least one active module unit as an independent unit from both the rotor and the stator. The active module unit includes at least one permanent magnet, a magnet support structure attached thereto, a first attaching mechanism to removably attach the magnet support structure to the rotor or the stator, at least one coil module comprising at least one coil winding and a magnetic core, and a second attaching mechanism to removably attach the coil module to the other of the rotor or the stator. The coil module is spaced apart from the permanent magnet a predetermined distance.
