Abstract
A synchro/resolver, preferably for use in combination with an identically constructed servo motor, having an annular stator with circumferentially arranged poles, each with its own coil winding thereon, and with the coils being connected in phases, an annular rotor positioned adjacent to the stator so that a change in rotational position of the rotor changes the inductance of the coil windings as a function of the rotational position of the rotor, and a detecting circuit for sensing alternating current flowing in each coil phase and for amplifying the differences between the currents in each phase to produce a rotational position output signal for commutating the motor.
