NASA lost contact with the MAVEN probe in Mars orbit, and teams are working to reestablish communications after an unexpected ...

Abstract: Aiming at the problem of high cogging torque of the conventional machine, this paper proposes a novel permanent magnet synchronous machine (PMSM) with the same number of poles and slots by ...

Abstract: This paper proposed the analysis of magnetic coupling force for an energy harvester with rotational frequency up-conversion structure. The harvester consists of a piezoelectric cantilever ...

The discovery of the rotational Doppler effect (RDE) has opened new opportunities for detecting parameters of rotating targets. In recent years, the physical mechanisms underlying this effect have ...
