Abstract
An electrically actuated continuously variable transmission (CVT) with an electric motor coaxially mounted on one of the pulleys of the CVT and having its rotor and stator both rotating with the pulley. One of two portions of the pulley is fixed-mounted on an engine shaft or other power source shaft, and the second is relatively axially movable with respect to the first. The rotor is rotatably fixed to the second pulley portion in certain embodiments, and is rotatably connected to it in other embodiments.
