Actuator having reduced dimensions and integrated locking of the motor with respect to the housing

Abstract

The invention relates to an actuator (1) for positioning an aeraulic flap, including a housing (10) containing an electric motor (30) surrounded by a shell (31) which is rigidly connected to a stator (33) of the motor (30) and which has one end closed by a cover (35), from which protrudes an output shaft (34) of the motor, the output shaft (34) being rotatably coupled to an input stage of an epicyclic reduction gear (50) having an external ring gear (52), the cover (35) including means (41) for locking said cover against rotation with respect to the shell (31), and said locking means (41) being arranged so as to also lock the external ring gear (52) against rotation with respect to the shell (31) of the electric motor (30).
