Abstract
PURPOSE: To enable a swift application of damping torque using a simple-design circuit, by differentiating the output voltage of a detector which detects the rotor position prior to stopage, the detecting the unipolar component of the differentiat voltage, and feeding the damping current to the armature coil.
