ABSTRACT:
A regenerative motor control of the field reversing type includes a field circuit for energizing the motor field and an armature circuit for energizing the motor armature. An analog signal generating means, typically a multiplier, is coupled to the armature circuit and is operable by a bi-polarity motor operative condition error signal and a bi-polarity field current direction and magnitude signal for energizing the motor armature and for providing deenergization, as well as improved reenergization of the armature, during the transient period between motoring and regenerative operation.
