Abstract

See full text

A motor driving device which can reduce a load burden on a rotating shaft when a magnetic bearing is initially operated. When a rotor and a stator are initially aligned, the motor driving device can apply a greater current to a coil positioned farthest away from the ground among a plurality of coils than to the other coils, so as to reduce a levitation force necessary for initial alignment of the rotor and the stator.
