ANGULAR OSCILLATION EIGHT-POLE ELECTROMAGNETIC VIBRATION MACHINE

A machine includes a stator 1 having equally disposed eight poles 1-1, 1-2, 1-3, 1-4, 1-5, 1-6, 1-7 and 1-8, and alternating current winding placed therewith coils creating two parallel branches, each wherefrom consists of coils and hub having eight poles 2-1, 2-2, 2-3, 2-4, 2-5, 2-6, 2-7 and 2-8 connected sequentially. The poles are located on the stator 1 and hub 2 so that the lines passing through the centers of opposite non-magnetic material gaps located between adjacent poles of parallel branches are the axes of symmetry. A winding placed on the poles of stator is directly switched to alternating current clamps 5-1, 5-2, and DC winding coils are placed on the poles of hub switched in sequence; furthermore, one branch coils of alternating current winding placed on stator poles, and direct current winding coils - on opposite armature poles are wound in parallel, and second branch alternating current winding coils placed on stator poles and, accordingly, opposite armature poles direct current winding coils are wound in parallel, that ensures constant current on the grips 5-3, 5-4 compensating self-induction EMF. Variable pole system is created as a whole so that capable to adjust of mechanical oscillations amplitude by chan¬ging the voltage on DC windings clamps.
