Toroidally Wound DC Brushless Motors

Moog Components Group toroidal motors have the dual advantage of being brushless and providing constant, ripple-free torque sustained through the required angle. Eliminating the slot cogging effect makes toroidal designs desirable in many applications, especially in incremental motion systems and in the field of control instrumentation. In addition, lower rotor inertia motors may be substituted where a high mechanical time constant was incorporated
to filter torque ripple.
