ABSTRACT:
A silent, high torque, impulse actuator system for low average power devices. The system incorporates a typical small three pole D.C. motor which has been modified to allow quick electrical conversion, with unipolar switching circuitry, from conventional rotation, to silent magnetic braking at a stop position; and then to a normally OFF condition.
The high efficiency of this intermittent drive system is enhanced by the unique combination of being normally off between actuations; the high efficiency of the D.C. motor during start conditions; and the use of a round cam to provide a cosine power stroke that utilizes the inertia of the motor rotor to maximum mechanical advantage.
