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.

Abstract: A method for fabricating a piston with a layering device via an additive manufacturing process is provided. The method may include forming a first layer of the piston on a substrate with a layering device, forming a second layer of the piston adjacent the first layer with the layering device, and binding the first layer with the second layer. The first layer of the piston may include a first material, and the second layer of the piston may include the first material and a second material.
