Abstract: An electromagnetic oscillation motor has an asymmetrical four-pole stator with an a.c. winding including two paths connected in parallel. Each path includes two serially connected coils received on the adjacent poles of the stator. The poles of the stator forming one pair are offset in opposite directions away from each other, while the poles forming the other pair are offset toward each other relative to the symmetry axes of their corresponding poles of the armature, through a distance equalling one half of the angular width of the stator winding. The oscillation motor further comprises a four-pole symmetrical armature, its poles being provided with a d.c. winding. The coils of this winding are connected in pairs in the matched-series fashion, while the pairs themselves are interconnected in opposition.
