ABSTRACT:
A synchronous reciprocating electric machine includes a first magnet system having first and second opposing surfaces forming between them a gap, and a second magnet system mounted within the gap so as to be displaceable relative to the first magnet system along a line of travel through the gap. The the first magnet system is configured for generating a magnetic field, referred to as the "gap field", directed across the gap primarily perpendicular to the first surface. The second magnet system includes two magnetic elements configured to generate equal but opposite magnetic fields primarily perpendicular to the first surface. These magnetic elements are spaced from each other along the line of travel by a distance b, where b>0. One of magnet systems produces a non-alternating magnetic field and the other is a coil assembly for producing an operating magnetic field. The machine also includes electrical connections connecting to the coil assembly so as to allow operation of the electric machine with reciprocation of the second magnet system relative to the first magnet system.
