ABSTRACT:
A torque control for an electromechanical torquing device of a type wherein there occurs variable clearance between a rotor and field. A Hall effect device senses the field present, which would vary as a function of spacing between field and rotor, and the output of the Hall effect device controls the power applied to the field so as to provide a well-defined field and thus a controlled torque to the rotor which is well-defined.
