Abstract
An electric rotary actuator, particularly for controlling a throttle cross-section in a line conducting operating fluid of an internal combustion engine has a housing, motor actuating unit including windings and magnetic poles located in the housing and magnetic armature rotatable relative to the windings and to the magnetic poles, a throttle. The housing has ducts leading into an interior space between the windings and each having an end at another end face of the armature. The armature has at least one cutout extending in an axial direction and bringable in alignment with the ducts. The armature forms the throttle member through which a fluid to be controlled is conducted.
