Rinehart Motion Systems is sharply focused on providing propulsion inverters and controls for electric (EV) and hybrid electric (HEV) vehicles. Our business is divided into three segments.
RM- family of ISO-16750 inverters tooled for low cost at production volume, production launch 2018
Provide supercar propulsion inverters to many different EV and HEV suppliers around the world
Product development engineering and production in vehicle propulsion, controls, and energy management Aerospace propulsion applications at low and high altitude, GaN and SiC inverters, SEB tolerance, SEU robust controls ISO26262 Automotive Functional Safety product development and safety 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, internal production capability, and manufacturing relationships with high volume 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.
