Abstract

The invention relates to a multi-pole electric motor with a rotor and a stator. Said stator consists of a plurality of coils and stator plates (1, 2, 3, 4) which are magnetically separate from one another and which extend from the coils to the rotor. The stator plates (1, 2, 3, 4) are linked with a non-magnetic metal fixture (11) in an area facing the rotor. According to the method of producing the electromotor described above, the stator plates (1, 2, 3, 4) which are interlinked by one or several webs (5) are produced as one workpiece, the workpiece is linked with the non-magnetic steel fixture (11) and the web(s) between or on the stator sheets (1, 2, 3, 4) is/are severed and/or completely removed.
