Abstract
The versatility and robustness with the low costs, characterize the synchronous reluctance SRM machines. On the other hand, some drawbacks limit the potential of such machines. A solution was found in the use of permanent magnets in the flux barriers. The adoption of traditional regular sintered magnets does not allow a complete filling of the flux barriers, therefore the adoption of bonded magnets has been proposed, and two different production technologies have been analyzed. Three prototype machines have been prepared: Reference SRM and two PM-assisted reluctance. Interesting results have been obtained from experimental tests and compared to FE simulation ones.
