Frost & Sullivan Recognizes Pioneering S-RAM Technology

Palo Alto, Calif. — Based on its recent analysis of the power supplies market, Frost & Sullivan recognizes Sanderson Engine Development, LLC (SED) with the 2008 North American Frost & Sullivan Award for Emerging Company of the Year. By designing the revolutionary Sanderson Rocker-Arm Mechanism (S-RAM), SED has successfully created a paradigm shift in the industry, and introduced a technology with disruptive market potential. The S-RAM is an emerging core technology for an entirely new generation of engine-driven pumps, compressors, generators, and any other device for which current power systems deploy multiple components (as in a crankshaft engine and a swash plate hydraulic pump) to transfer power.

LSHT Motor Tests Show Impressive Performance

Palo Alto, CA — Hydraulics & Pneumatics Magazine:

The latest tests of a recent invention, the Sanderson rocker-arm mechanism (SRAM), Figure 1, show advantages for this method of converting reciprocating motion into rotary motion. The low frictional losses of the SRAM pay off in high torque and overall efficiency in hydraulic devices, and may lead to lower heat generation and higher starting torque than with conventional motors and pumps.
