Brief History
Robert Sanderson invented the Sanderson Mechanism following a breakthrough insight in 1997. He envisioned a unique rocker arm design that can be applied to any design that presently uses a crankshaft, bent axis, swash plate, or wobble plate to convert reciprocating motion to rotary motion and vice versa. An initial gasoline engine prototype began testing in May 1998. By December 1998, the engine had been tested at speeds from 300 to 1900 rpm with torque as high as 120 ft/lb and demonstrated its superior mechanical efficiency.
In 7 years of operation, Sanderson Engine Development, LLC (SED) has received multiple patents, successfully tested prototypes under a wide range of conditions, and signed development agreements with major US companies. The Sanderson Mechanism has proven scaleable and widely applicable beyond engines. Development projects by licensees range from 500 horsepower pump to 5 HP compressors, from a hydrostatic transmission to refrigeration systems.
SED’s business model is to license the technology in exchange for future royalties. Other than building prototypes for certain customers, SED does not plan to manufacture products.
