Abstract

A permanent magnet reciprocating engine and method are provided wherein a first field plate having magnetic fields of two polarities interact with the magnetic field of a magnet located on a piston plate. The first field plate is moved to alternately bring the magnetic field of a first polarity and the magnetic field of a second polarity into alignment with the magnetic field of the piston plate, thus alternately attracting and repelling the piston plate to the field plate. The piston plate is connected to a piston rod, which reciprocates along an axis as a result of the alternately attractive and repulsive forces exerted on the piston plate by the field plate. A translation mechanism, such as a crankshaft, translates the linear motion of the piston rod along the axis into rotary motion that can be harnessed as power.
