ABSTRACT:
A multiple phase electronically commutated torque motor including an annular stator element having at least two coils or windings on the periphery thereof and a magnetic rotor disposed concentrically within the stator for relative coplanar rotational motion. Means are provided for selectively energizing and de-energizing the windings as a function of the instantaneous rotor angle on command to generate a desired torque.
