A closed loop resonance compensation method and circuit for a stepper motor stabilizes the stepper motor control system while operating in the mid-frequency range. The stepper motor stabilization method and means corrects for mid-frequency resonance errors by deriving a velocity error signal from the total current in the motor windings and uses this signal, through feedback to the source of clock pulses, to correct the short term rotor velocity with respect to the stator field.
