PCT No. PCT/EP88/00086 Sec. 371 Date Aug. 11, 1989 Sec. 102(e) Date Aug. 11, 1989 PCT Filed Feb. 5, 1988 PCT Pub. No. WO88/06375 PCT Pub. Date Aug. 25, 1988.The invention relates to an alternating current motor comprising a rotor having an exciter part arranged therein and a stator having two fixed armature coils wherein each of the coils is surrounded on three sides by U-shaped soft iron elements forming the stator poles and air gap. The free ends of the soft iron elements are shifted by one pole division against one another. A series of soft iron blocks form the exciter poles with the polarity of the poles alternating along the direction of rotation. Between the soft iron blocks of the rotor exciter part are arranged permanent magnets magnetized with alternating polarity wherein the face surface of the permanent magnets lying opposite the soft iron blocks is greater than half the face surface of the exciter poles formed by the soft iron blocks on the air gap.
