ABSTRACT:
A torque motor incorporating a permanent magnet rotor and winding therewith for providing the indicating mechanism of a servoed indicating unit. The circuitry for use with the indicating mechanism first applies a reference feedback-producing pulse, then provides the signal for application of torque to the indicator to move it toward the desired position, and then has a quiescent period to clear the stator windings of the mechanism of currents before recommencing the voltage reference and torquing cycle.
