Abstract: A linear motor for moving a piston rod of a reciprocating compressor. The motor includes a guidance assembly having a moveable secondary carrier that is attached to the piston rod. The motor also includes at least one permanent magnet attached to the secondary carrier and at least one primary winding attached to the guidance assembly. In addition, the motor includes a controller that controls power supplied to the primary winding to generate a magnetic field that interacts with a magnetic field generated by the permanent magnet to provide a force that moves the permanent magnet, the secondary carrier and the piston rod in a reciprocating linear motion.
