Abstract :
The paper intends to re-design a permanent magnets synchronous generator (PMSG) having low efficiency, in order to bring it in the range of actual generators. The starting point was a real machine which was transformed from induction machine into permanent magnets machine for series production. It had low efficiency and low power factor. By following the operational aspects of the machine and the theoretical phenomenon presented by electrical machines manufacturers, the machine was re-designed and a superior efficiency was obtained.
