Abstract

Drive having a commutated electric motor (10), having a coaxial gearing (20) which is connected to the electric motor (10) and which comprises: an internal gear with an internal toothing (5); a tooth carrier (11) in which there are received a multiplicity of teeth (7) for engagement with the internal toothing, wherein the teeth are mounted so as to be radially displaceable relative to the tooth carrier (11) in the longitudinal direction of the teeth (7); a drive-input element with a profiling (22) for the radial drive of the radially displaceably mounted teeth (7), and having a gearing rotary encoder (30) which is connected to the drive output (25) of the gearing (20), wherein the gearing rotary encoder (30) is arranged and designed to detect a drive-output angular position and to output said drive-output angular position as a drive-output angle signal (δ).
