Abstract

An electromagnetic rotary drive, designed as bearingless motor, is proposed which comprises a magnetically journalled rotor (3) and a stator (2) which comprises a drive winding for producing a magnetic rotary drive field which produces a torque on the rotor (3), and a control winding for producing a magnetic rotary control field by means of which the position of the rotor (3) with respect to the stator (2) can be regulated, with the stator (2) having exactly six stator teeth (21).
