Abstract
An electric control motor is proposed, which serves to adjust final control elements in closed- or open-loop control systems, in particular for varying the position of throttle devices provided for metering fuels in internal combustion engines. The control motor includes a housing, in which an electromagnetic coil and an armature are disposed, the armature being rotatably supported upon a shaft providing spaced air gaps therewith and with magnetic poles. The magnetic poles are disposed on arcuate conducting bodies, which are disposed in spaced relation on a nonmagnetic carrier body. At ends remote from the magnetic poles, the conducting bodies communicate with one another via a magnetically conductive plate.
