Abstract
A direct current motor control circuitry provides linearity between an input signal to the circuitry and torque developed in the motor energized by the circuitry. A signal divider algebraically divides a numerator signal by a denominator signal and provides a quotient signal as the output. The input signal is provided to the signal divider as the numerator signal. A field circuit energizes the field winding of the motor. An armature circuit energizes the armature winding. One of the field or armature circuit provides a signal proportional to the respective one of field current or armature current to the denominator input of the signal divider. The signal divider is connected to the other of the field circuit or armature circuit for establishing the field current or armature current in accordance with the output quotient signal.
