INTEGRATED LINEAR GENERATOR SYSTEM
An integrated linear generator system includes, for example, a generator assembly, a control system, a frame system, an exhaust system, an intake system, a cooling system, a bearing system, one or more auxiliary systems, or a combination thereof. The generator system is configured to generate power, as controlled by the control system. The generator assembly may include an opposed- and free-piston linear generator, configured to operate on a two-stroke cycle. The intake and exhaust systems are configured to provide reactants to and remove products from the generator assembly, respectively. The cooling system is configured to effect heat transfer, material temperature, or both, of components of the integrated linear generator system. The bearing system is configured to constrain the off-axis motion of translators of the generator assembly without applying significant friction forces. The frame system is configured to manage rigidity, flexibility, and alignment of components of the integrated linear generator system.
1 . A linear generator comprising:
a structural frame;
a cylinder affixed to a center region of the structural frame;
a first linear electromagnetic machine (LEM) arranged on a first longitudinal side of the cylinder, and affixed to the structural frame; and
a second LEM arranged on a second longitudinal side of the cylinder, and affixed to the structural frame, wherein the second longitudinal side is opposite the first longitudinal side, wherein the second LEM is aligned to the first LEM, and wherein the cylinder is aligned to the first LEM and to the second LEM.
