Design and study of effect of magnetic flux-barriers on a high-pole Permanent Magnet Synchronous Machine

This paper presents the design of a permanent magnet synchronous machine, with a 28-pole fractional slot concentrated wound machine as reference. The new stator structure is based on the principle of magnetic flux-barriers in the stator core, whose effect on the air-gap flux density harmonics is studied. The output parameters analysis of the two machines indicates that the new stator model presents significant advantages.
