The paper presents the results of energy efficiency and traction evaluation of linear induction machines for with molten aluminum recycling furnaces. Ansys Maxwell software was used for the synthesis of 3D parametric models of electromagnetic fields for a large air gap furnace. Interchangeable modules of three-phase transverse and longitudinal field inductors were used as a subsystem of a parametric model. Both inductor models include invertor low frequency power supply. Transverse and longitudinal field inductors have been designed with similarity principles. A stationary electromagnetic mode and power parameters has been modeled without taking melt hydrodynamics into account. Linear induction transverse-field machines have demonstrated higher efficiency.
