Abstract
A linear electric motor, capable of producing reciprocation of a piston within a cylinder to compress refrigerant gas. The coil of the linear electric motor is mounted to the internal wall of a block that forms the cylinder of the compressor, and a support for the magnets is mounted to an outwardly extending base flange of the piston. The support is formed by a base plate mounted to the base flange with a plurality of 'L' shaped finger plates spaced around and affixed to the base plate, with the edges of the long legs of the finger plates extending radially of the piston's central axis. Arcuated shaped permanent magnet are fitted between the opposite flat sides of each pair of the long legs of the finger plates to form a stable and rigid toroidal shaped magnet assembly positioned between the external wall of the cylinder and the coil.
