A control circuit for a stepping motor is provided which rotates the motor armature in such a manner as to minimize motor resonances while not appreciably reducing the motor torque at high speeds. The motor inherently possesses a non-linear transfer function of current to flux and the circuit includes means responsive to an input signal for developing a position command signal which is a sinusoidal waveform modified by the inverse of the motor transfer function. Further means are provided responsive to the position command signal for developing an energization signal for the stepping motor including means responsive to the position command signal and motor field current for terminating a motor energization cycle.
