Abstract :
We propose a new electromagnetic pump, applicable to high-temperature molten metal in cylindrical ducts. A rotating twisted magnetic field is generated by the stator with three pairs of helical windings. Axial thrust, as well as rotational torque, acts on the secondary conductor. It is verified that the thrust is actually obtained in experiments with a prototype stator and solid secondary conductors (bulk rotors). We discuss the slip-thrust curve for various conductivities of the secondary conductors
