Abstract

See full text

A method for positioning a brushless electric drive comprising a stator that has at least one phase winding to which a voltage signal can be applied, and a rotor equipped with magnetic poles. In the method, a voltage signal is applied to the at least one phase winding, the voltage signal generates a magnetic field as a result of the current flowing in the phase winding. The magnetic field putting the rotor into alignment, and as long as the rotor is in motion, the voltage signal is modified in accordance with the intensity of the current induced in the at least one phase winding by the moving rotor, in such a way that the induced current is increased.
