Cover Story (view full-size image): This paper proposes a procedure for computing magnetic losses in coaxial magnetic gears. These magnetic structures are made of permanent magnets and ferromagnetic poles in relative motion, transferring torque between two shafts in a contactless way. The loss computation of magnetic materials is crucial for defining system performance. This computation is performed by applying a model of iron loss while taking into account the rotational nature of the flux loci. The procedure highlights the location of major loss sources and provides the opportunity to evaluate some corrective measures to reduce their effects. View this paper.
