Abstract

Electrical machine (10), and also method for producing an electrical machine, in particular for adjusting moving parts in a motor vehicle by motor, having a stator (12) into which a rotor (14) can be inserted, wherein the stator (12) has two permanent magnets (18) which are situated opposite one another and which are arranged in a pole housing (16) which forms a magnetic return path, and the pole housing (16) has flattened regions (20) between the two permanent magnets (18), the pole housing wall (26) forming two magnetic follower poles (22), which are situated opposite one another, on the said flattened regions, wherein the maximum dimension (25) of the pole housing (16) between the two flattened regions (20) which are situated opposite one another—axially in the region of the follower poles (22)—forms a width (24) across flats for the installation space of the electrical machine (10) which is equal to a maximum of 35 mm—and in particular a maximum of 30 mm.
