Abstract
The adoption of assisted reluctance machines in various applications is becoming popular. The use of permanent magnets in synchronous reluctance machines allows to resolve some drawbacks and improve the performance; in general, sintered magnets with regular shape have been adopted. On the other hand, this approach does not permit to fill completely the flux barriers. The proposed solution consists in the use of bonded magnets. Two types of ferrite magnets, sintered and bonded, have been considered in the study. Different parameters have been investigated, both in the production process and in the performance evaluation. The simulation results have been compared to the reference synchronous reluctance machines. A prototype machine has been prepared and different experimental tests have been performed. Good matching between measurement and simulation results has been observed.Pubblicazioni consigliate
