ELECTRIC ACTUATOR FOR ENGINE CONTROL

摘要

An electric actuator (112) for control of an engine includes an electric motor coupled to a drive shaft (204) that extends to align a gear interface (140) of the electric actuator with a variable geometry adjustment interface of the engine. A position feedback shaft (206) extends coaxially with respect to the drive shaft. The position feedback shaft is coupled to an output shaft of the gear interface (140) 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 (204) and the position feedback shaft (206) are sized to position an output ring gear (218) 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.
