ABSTRACT:
An electromotor including a stator (32) having a central receiving region for a rotor (23), at least two, projecting into the rotor-receiving region, stator pole pairs (18, 19, 20, 21), an insulation element (1, 2) provided at each end side of the stator (32), a stator winding (16, 17) surrounding a stator pole pair (18, 19, 20, 21) and a portion of a respective insulation element (1, 2), a permanent magnet (14, 15) between a pair of adjacent stator poles (18, 19, 20, 21), and dielectric support elements (7, 8) cooperating with respective insulation elements (1,2) and arranged along the main axis of the rotor-receiving region of the stator (32) between side surfaces (28, 29, 30, 31) of the stator poles (18, 19, 20, 21), which extend substantially parallel to the main axis of the rotor-receiving region of the stator (32) and to each other, and the stator windings (16, 17), respectively.
