TRANSFORMER CONVERTER Russian patent published in 1997 - IPC

FIELD: vibration engineering, watch and clock engineering, instrumentation engineering. SUBSTANCE: two similar spiral springs 3, 4 embrace opposite columns of magnetic core 1 on one plane and internal ends 5, 6 of each spring are rigidly coupled with core 1. Springs are arranged so that they are wound in opposite directions and electrically shorted out by external ends 7, 8 which are also coupled mechanically and in symmetrical opposition with shaft 9 which is free to vibrate on its supports. Passing AC current through winding 2 winds up and upwards springs 3, 4 placing shaft in vibratory and rotary motion. EFFECT: improved design. 3 cl, 2 dwg
