Rinehart Motion Systems is sharply focused on providing propulsion inverters and ancillary power electronics assemblies for new and emerging applications of electric (EV) and hybrid electric (HEV) ground vehicles. Our business is divided between professional motorsports (we have provided KERS hybrid hardware to the Formula One grid since the 2009 race season, presently servicing 3 teams and in six cars every race); standard products (our PM family of 50kW – 250kW motor controls designed to ISO16750 commercial vehicle standards); and custom products (primarily military ground vehicle propulsion components, OEM automotive power electronics and propulsion hardware, and product development in vehicle controls and energy management).
Founded in 2002, the company has developed a unique packaging approach (with 6 issued Patents to date) and has established a TS16949-compliant new product realization process and manufacturing relationships with TS-certified automotive production facilities in the US, Asia and Europe. RMS drives are typically half the size and weight, are more rugged, and are generally easier to use than competitive products. The company also provides unique customization services – offering new software features, communications protocols, custom housings and specialized functionality for different applications.
