Abstract
A method by means of which the damping of the rotor and of the load of a multiphase motor can be increased when it is desired to stop the rotor and the load in a certain position consists in measuring the voltages induced by the movement of the rotor in the different stator phase windings and modifying the currents applied to these windings as a function of the measurements made, so as to produce an electromagnetic-type damping torque. A device for carrying out this method comprises circuitry for measuring the induced voltages in the phase windings and circuitry by means of which currents depending on such measurements of the induced voltages can be applied to these phase windings.
