Electronically controlled actuator

摘要

An electronically controlled actuator for controlling a turbocharger is provided. A motor (130), a speed change mechanism (140) and a position sensor (150) are contained in a case consisting of a body (110) and a cover (120). The driving force of the motor (130) is transmitted through the speed change mechanism (140) to an output shaft (145) to drive the movable vanes of a turbocharger for turning. A first bearing (146A) supporting the output shaft for rotation is held on the cover (120), and a second bearing supporting the output shaft for rotation is held on the body (110). The position sensor (150) is mounted on the output shaft of the motor (130). The reliability of the actuator is improved.
