Abstract

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.

Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 171 words
An electromagnetic oscillation motor comprising a symmetrical four-pole armature with a DC winding and an asymmetrical four-pole stator with an AC winding made up of two parallel-connected paths, each said path including two series-connected coils (12, 13 and 14, 15), characterized in that the adjacent stator poles (3, 4) forming one pair are offset in opposite directions, while adjacent poles (5, 6) forming another pair are offset toward each other with respect to the axes of symmetry of respective poles (8, 9 and 10, 11) of the armature to a distance (b/2) equal to one half of the width (b) of stator poles, each path of the AC winding being received on the respective pair of adjacent stator poles (3, 4 and 4, 6), and, the coils (18, 19 and 20, 21) of the DC winding are connected in pairs in a matched-series fashion and received on the adjacent poles (9, 10 and 8, 10) of the armature, the pairs of coils (18, 19 and 20, 21) being connected in opposition.
