Influence of the amount of permanent-magnet material in fractional-slot permanent-magnet synchronous machines [PDF]

open access: yes, 2014
The efficiency of permanent-magnet (PM) synchronous machines with outer rotor and concentrated windings is investigated as a function of the mass of magnets used, keeping the power, volume, and mechanical air-gap thickness constant. In order to be useful
