In an electromagnetic suspension device comprising one member (1), the other member (2) adapted to perform a relative motion with respect to the one member (1), and a motor (M) capable of at least suppressing the relative motion, and wherein electric current values id and iq of d and q phases are determined using dq conversion from electric currents iv and iu flowing in the motor (M) and an electrical angle theta of a rotor, and the motor (M) is controlled on the basis of both d-phase voltage command value Vd1 and q-phase voltage command value Vq1, the improvement characterized by further comprising correction means (23) for correcting the d-phase voltage command value Vd1 on the basis of both q-phase electric current iq and electrical angular velocity omega of the rotor and correcting the q-phase voltage command value Vq1 on the basis of both d-phase electric current id and electrical angular velocity omega of the rotor.
