Abstract
A machine includes at least one piston (1) reciprocally movable in a cylinder (2), at least two balancing rotors (3c, 3d) mounted for oscillating rotational movement about an axis or axes (4) transverse to the axis of motion of the piston, one balancing rotor having a centre of mass on one side of and another balancing rotor having a centre of mass on an opposite side of the axis or axes of motion of the rotors, and at least one connecting member or mechanism between the piston and rotors so that the rotors move in opposition to the reciprocal movement of the piston. The machine may be an electrical machine such as an electric motor or generator. An electronic control system may control piston motion or output waveform.
