Spinup of rotors in devices with noncontact suspension

Komarov Valentin Nikolaevich, Lobachevsky State University of Nizhny Novgorod

In the paper one of ways of spinup of rotors in devices with noncontact suspension is considered. For the creation of rotation the pulse-position way of control the fields of stator’s coils is applied. The method of approximation of limiting cycles by the Fourier series is carried out for the theoretical investigation of an opportunity of realization of the suggested way. The algorithm of control the coils fields is found and the conditions imposed on the parameters of the working moments which allow to receive the maximal angular speed of the rotor at the minimal power inputs are received. Investigstion is carried out for one, two and several pairs of control coils.
