Abstract
An electromagnetic adjustment device for performing mechanical rotational movements has two electromagnetically excitable pole pieces arranged opposite each other to form an opening partially surrounded by concave circular surfaces of the pole pieces. A rotary anchor of permanent magnetic material is rotatably supported in the opening. The anchor has two opposite circular surface sections and two opposite flat surface sections. The flat surface sections face the concave circular surfaces of the pole pieces when the rotary anchor is in a position signifying a center of its operational range. The radius of the concave circular surfaces is slightly larger than the radius of the circular surface sections of the rotary anchor forming north and south poles so that four air gaps are formed between the concave circular surfaces of the pole pieces and the circular surface sections of the rotary anchor.
