Abstract
A variable output planetary gear set includes an input shaft, and input gear affixed to the input shaft so as to rotate with a rotation of the input shaft, a brake rotor, a rotor input gear affixed to the brake rotor, a planetary gear set, an output shaft cooperative with the planetary gear set, and an electromechanical brake cooperative with the brake rotor so as to selectively apply a braking force so as to slow a rotation of the rotor input gear. The electromechanical brake is, in particular, an eddy current brake. The planetary gear set includes a planetary input gear, a planetary carrier, plurality of planetary gears, a sun gear and a ring gear. The input gear is engaged with the planetary input gear. The ring gear is engaged with the rotor input gear.
