Latest Patents

One of Shrago's latest patents is the "Long life seal and alignment system for small cryocoolers." This invention features a compressor that includes a motor assembly designed to compress gas within a compression volume. The motor assembly consists of a stationary coil assembly and a moving assembly with at least one magnet. The design allows the moving assembly to reciprocate axially, adjusting the gap between the stationary coil and the moving assembly to provide magnetic axial stiffness. This technology can be utilized in various cryocooler assemblies.

Another significant patent is the "Low vibration cryocooler." This invention discloses a Stirling class cryocooler that incorporates a motor driving a mass. The motor features a main drive winding and a separate trim winding. A motor controller outputs a main drive signal to the main drive winding and a vibration-reducing signal to the trim winding, effectively minimizing vibrations in the cryocooler.
