Danfoss
Danfoss Power Solutions, previously known as Sauer Danfoss, is a world leader in producing hydraulic systems for the construction, agriculture and mobile equipment industries. Danfoss Power Solutions has more than 3000 different types of orbital motors, varying in size (rated displacement), speed, operating torques and maximum outputs. [1]
Danfoss orbital motors variety Minimum value Maximum value
Displacement 8 cm3 800 cm3
Speed 600 rpm 2500 rpm
Torque 13 Nm 2700 Nm
Power 2.0 kW 70 kW

One of the company’s priorities is to give the best-in-class efficiencies, leading to energy savings. The European emission standards are strengthening the limits with every year. For less than 10 years – in the period 2004 - 2012 – the limits for Hydrocarbons (HC) have been reduced nearly 7 times, for nitrogen oxides (NOx) - twice and particulates (PM) more than 24 times. A short summary of the emissions regulations relevant for Danfoss orbital motors is given bellow.[2]
