Abstract
An electromechanical transducer apparatus for converting between mechanical energy and electrical energy is disclosed and includes first and second magnetic flux generators including pole pieces coupled to direct magnetic flux. The magnetic flux generators are disposed such that opposite polarity pole pieces are spaced apart in adjacent relation. A pair of reciprocators are coupled for reciprocating movement between the pole pieces and are spaced apart by first and second air gaps. A closing piece completes a magnetic circuit and when the reciprocators are disposed such that the first air gap is smaller than the second air gap, magnetic flux generated by the first magnetic flux generator flows in a first direction via the first air gap through the closing piece. When the reciprocators are disposed such that the second air gap is smaller than the first air gap, magnetic flux generated by the second magnetic flux generator flows in a second opposite direction via the second air gap through the closing piece. A current carrying coil is disposed to electromagnetically interact with the magnetic flux.
