Abstract
Theoretical and experimental modelling investigations have demonstrated that electromagnetic induction pumps based on the principle of rotating permanent magnets (PMP) have many advantages in comparison with traditional linear inductor pumps [1]. For the so-called disc type pump design concept, a mathematical model on the distribution of magnetic field induced electrical currents and electromagnetic forces has been developed to calculate the pressure-flow rate characteristics of the pump.
