Abstract

The through magnetic conductivities of a modulator have been considered in the magnetic fluxes produced by the stator winding and rotor magnets at observation points that are located on the outer surface of magnets and bore surface of a stator, respectively. The numerical calculations have shown that these conductivities, which substantially differ from each other, are formed by the fundamental harmonics. The contribution of higher harmonics in these conductivities is negligible. The analytical calculations of the through magnetic conductivity of a modulator (based on the classical approaches to electrical machines for calculations of magnetic fields in air gaps with single-sided serration) lead to a significant error. The effect of magnetic saturation of the modulator cores made of laminated electric steel sheets on the through magnetic conductivities has been estimated.
