CONTROLLED VELOCITY ACCESSORY DRIVES – SOLVING THE POWER-AT-IDLE CHALLENGE

Orbital Traction demonstrated through a Phase I SBIR the feasibility of a controlled velocity accessory drive (CVAD) that enables a heavy duty alternator to produce full rated power at engine idle and across the full range of engine speeds. Orbital Traction’s CVAD is based on a novel, continuously variable transmission and can be applied to other engine accessories and OBVP applications.
