To damp oscillations of a stepper motor

摘要

In the case of a stepper motor having a stator magnetic field rotating in order to cause the rotor, a method for damping the reciprocations of the rotor, which occurs when the magnetic field of the stator is stopped arriving at an angular position desired, consists in measuring quantities instant relating to the speed of the rotor due to oscillations that - latter about the angular position desired, to remove the magnetic field of the stator from the angular position desired in a direction opposite to the direction of the oscillations, and then returning the magnetic field of the stator has the position of stoppage desired.
