Abstract: This article presents a contra-rotating (CR) brushless integrated flux-modulation (BIFM) machine with an open-slot structure for wind power generation, termed CR-BIFM machine. The presented ...
Researchers at SINTEF have now designed and built new measuring equipment for testing contra-rotating propellers, which are propellers that rotate in opposite directions. This could be good news for ...
Abstract: This paper aims to investigate the vibration performance of an axial flux permanent magnet synchronous machine (AFPMSM) with two contra-rotating rotors. A rapid analytical model of the ...
