Abstract
The invention is a system for gearless operation of a movable barrier utilizing Lorentz forces, and in particular, a movable barrier operator retrofitted with a gearless motor capable of high torque at very low speeds. Eliminating a gear system in accordance with the present invention lowers maintenance requirements, increases efficiency, and streamlines operation of any movable barrier. By utilizing a motor which produces high-torque at low a speeds a system in accordance with the present invention does away with the need for complicated gears and pulley systems in order to achieve control of movable barriers. The present invention allows manufacturers, distributors and consumers to implement movable barrier systems with much more versatility and efficiency.
