Abstract (en)
[origin: EP2216107A1] The system (1) has a pair of identical cranks (4', 4'') rotating about respective crank axes offset from a reciprocal frame (10), and connecting rods (7', 7'') connected between the cranks and the frame. Counterweights (5', 5'') are placed in the cranks opposite to respective arms, and crank drive (3', 3'') i.e. non-set slider crank drive, are driven by electric motors (6', 6'') i.e. slow high-torque electric motors, to rotate about the respective axes in opposite rotational directions. Single-stage helical-gear trains (9', 9'') are equipped between the electric motors and the cranks.
