Description
The Froude Hofmann AG150HS eddy current dynamometer is rated at 150 kW (200 bhp) and has a maximum operating speed of 12,000 rpm. It is one of a range of dynamometers that have been designed specifically for testing engines and their components in many applications including Research and Development, Quality Audit, Endurance, Production and Overhaul.
AG dynamometers range 30 to 750 kW (40 to 1010 bhp). Power absorption can be in either direction of rotation and standard or high-speed versions are available to meet individual testing requirements. Operating in numerous test cells throughout the world, Froude Hofmann AG dynamometers have demonstrated themselves to be a first class investment providing accurate performance and cost effective, reliable service.
