Abstract: An electric actuator for control of an engine includes an electric motor coupled to a drive shaft that extends to align a gear interface of the electric actuator with a variable geometry adjustment interface of the engine. A position feedback shaft extends coaxially with respect to the drive shaft. The position feedback shaft is coupled to an output shaft of the gear interface at a gear interface end of the position feedback shaft. A rotational position sensor is coupled to a motor end of the position feedback shaft proximate the electric motor. The drive shaft and the position feedback shaft are sized to position an output ring gear of the output shaft in contact with the variable geometry adjustment interface within a casing of the engine and to further position the electric motor and the rotational position sensor external to the casing of the engine.

Abstract: An inverted harmonic gear actuator is provided and includes a motor stator and a motor rotor radially disposed within the motor stator. The inverted harmonic gear actuator also includes a wave generator radially disposed within the motor rotor, where the wave generator has a radially inner surface with a cammed shape. An actuator output shaft is radially disposed within the wave generator. A flex spline is radially interposable between the radially inner surface of the wave generator and the actuator output shaft. The flex spline is deformable to conform to the radially inner surface of the wave generator and drive rotation of the actuator output shaft slower than rotation of the motor rotor.
