Abstract
Induction pumps are most promising electromagnetic pumps for use in power plants with sodium as a coolant liquid. These pumps usually contain an iron core in stators. This paper aims to investigate an electromagnetic pump with core-free double stator design. Numerical results show that such pump configuration is of particular interest, it exhibits little efficiency decrease if compared to standard electromagnetic pumps, eliminates magnetic field limitation due to saturation and decreases design complexity. The velocity field in the core-free pump is smoother than in the standard pumps. Tables 2, Figs 9, Refs 46.
