Abstract
A linear compressor is provided. The linear compressor includes a casing that defines a chamber and a piston slidably received within the chamber of the casing. A driving coil is configured for selectively urging the piston to slide within the chamber of the casing. An electro-magnetic spring is configured for urging the piston towards a default position when the piston is positioned away from the default position. The electro-magnetic spring can permit the linear compressor to operate at a resonant condition.
