Abstract

An apparatus in accordance with the invention includes a motor and a gearbox coupled to the motor and comprising an output shaft configured to actuate a window covering. A position encoder, directly driven by the output shaft, is configured to measure at least one of an angular position and a number of rotations of the output shaft. The angular position and number of rotations may be used to calculate an angular position of slats of a window blind and/or an amount a window covering is opened or closed. A corresponding method is also disclosed herein.
