Electric machine sizing consideration for ePumps in mobile hydraulics
Energy Science &Engineering, Volume 12, Issue 3, Page 793-809, March 2024.This research examines the energy efficiency and design of various ePump architectures for off‐road vehicles, with a special focus on those integrating permanent magnet synchronous machines and axial piston machines. The study reveals that variable displacement ePumps can cut electrical machine size by up to 40% under certain conditions, while the ...
