This paper presents part of a study aiming to identify whether 'Dual Stator Spoke Array Vernier Permanent Magnet' (DSSAVPM) generators present an advantage, regarding size or cost, as compared to the conventional radial flux PM machine for direct drive applications. For this purpose, design of both machines is optimized for the same specifications and using the same design criteria. optimization results are presented and discussed. It is found that a DSSVPM generator design, with almost the same performance as the RFPM generator, but with 45% of its mass is possible. © 2018 IEEE.eninfo:eu-repo/semantics/closedAccessdirect drivegenerator designmagnetic gearingpermanent magnetvernier effectConference ObjectN/AN/A4453
