Chet Seymour, Application Engineer, Sauer-Danfoss:
"Advancing Hydraulic Technology into the Age of Hybrid Vehicles and AC Drives"
Upcoming TIER 4 engine changes will necessitate cooling system upgrades in most engine powered machines. Application of multi-kilowatt alternating current motors in off-road mobile equipment offers significant rewards and challenges. Fan drives in mobile equipment will be one of the first stepping stones into vehicle electrification for many OEMs. Electrically driven fans offer better design flexibility while reducing fuel usage and lower parasitic losses than other fan drive technologies. These rewards come with various design challenges that will also be discussed.
