Abstract

A three-phase inductor which generates a magnetic traveling field is often used in induction liquid metal pumps. Due to the finite length of the inductor an alternating magnetic field component occurs, which should be compensated. An analysis of the electromagnetic field of an induction pump with a rectangularly shaped transport channel and a flat three-phase inductor possessing a compensating winding is presented. It is based on a computational model which takes into account the finite length and width of an inductor winding and nonuniform velocity distribution along the liquid metal depth. The calculations of magnetic flux density distributions in liquid zinc were carried out for an induction pump with and without compensating winding
