ELECTRODYNAMIC LEVITATION EFFECT IN VERTICAL HTSC ALTERNATORS WITH AXIAL MAGNETIC FLUX

Abstract

Vertical electrical alternators with axial magnetic flux and disc geometry of the rotor and the stator are characterized by the presence of electrodynamic force, which is acting perpendicular to the active zone elements. It depends mainly on the load angle value, magnetic flux density in the air-gap and armature current value. The presence of this force is to be accounted for during the alternator development and testing.
