Abstract
A linear compressor is provided. The linear compressor includes an electro-magnetic spring and a casing that defines a chamber. A piston is received within the chamber of the casing. The electro-magnetic spring can apply a non-linear force to the piston such that a total spring force applied to the piston during a compression stroke is substantially linear.
