Orbital Hydraulic Motor

Dan-foss is a world leader within production of low speed orbital motors with high torque. We can offer more than 3000 different orbital motors, categorised in types, variants and sizes (incl. different shaft versions). The motors vary in size (rated displacement) from 8 cm³ [0.50 in³] to 800 cm³ [48.9 in³] per revolution. Speeds range up to approx. 2500 min-1 (rpm) for the smallest type and up to approx. 600 min-1 (rpm) for the largest type. Maximum operating torques vary from 13 N•m [115 lbf•in] to 2700 N•m [24.000 lbf•in] (peak) and maximum outputs are from 2.0 kW [2.7 hp] to 70 kW [95 hp].

Characteristic features of Dan-foss Orbital Motors • Smooth running over the entire speed range • Constant operating torque over a wide speed range • High starting torque • High return pressure without the use of drain line (High pressure shaft seal) • High efficiency • Long life under extreme operating conditions • Robust and compact design • High radial and axial bearing capacity • For applications in both open and closed loop hydraulic systems • Suitable for a wide variety of hydraulics fluids Technical features of Danfoss Orbital Motor The programme is characterised by technical features appealing to a large number of applications and a part of the programme is characterised by motors that can be adapted to a given application.
