Abstract

The invention relates to an electric drive (2) comprising: a stationary outer stator (20) and an inner stator (96), and a rotor (50), which comprises a ferromagnetic rotor sleeve (56) to which permanent magnets (62) are attached on the side facing the outer stator (20); and a rotation-translation transmission (78), which comprises a spindle (80) co-rotating with the rotor (50), and a nut (86) that can be rotated relative to the spindle (80). The aim of the invention is to provide an electric drive of said type which has as little inertia moment as possible and is easy to manufacture. For this purpose, the inner stator comprises an anti-turn device for the nut (86).
