Abstract
The tendency of a stepping motor to oscillate or flutter under some mid-velocity conditions is minimized by reducing the deviation of the motor's rotor from its normal synchronous position by altering the time about a nominal time when a change of energization of the motor's windings is to occur after receipt of an input pulse in accordance with the duration of the decay current that existed at the prior change of energization.
