VMR Orbital Motor
A wide range of Orbital Motors Characteristic, features and application areas of Orbital Motors
Danfoss 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 Danfoss 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. Adaptions comprise the following variants among others:

Technical Information
VMR Orbital Motor
Data survey Introduction By introducing the VMR, Danfoss is introducing an Orbital Motor in the new V-Series. In order to meet the demands for motors that have the right duty cycle and efficiency capabilities for a given function, Danfoss now has 3 Orbital Motor Series: T-Series – The Highest Torque Leading performance with a long lifetime makes light work of the heaviest duties. Offering pressure capability up to 350 bar [5076 psi] and high starting torque, the T-Series is the energy-efficient choice for the toughest working environments. O-Series – The Flexible Choice The O-Series is flexible beyond compare. Delivering premium power across the board, these motors cover small to large, medium to heavy-duty needs with pressure capability up to 275 bar [3990 psi]. Robust, reliable and designed to fulfill the latest emissions standards. V-Series – The Core Solution The V-Series is your quality benchmark in the medium duty market. Based on proven technology, these reliable motors will reduce your overall system costs while adding value to your machine. Perfect for many tasks. VMR features

Speed, torque and output
Speed, torque and output The bar diagrams, are useful for a quick selection of relevant motor size for the application. The final motor size can be determined by using the function diagram. The function diagrams are based on actual tests on a representative number of motors from our production. The diagrams apply to a return pressure between 5 and 10 bar [75 and 150 psi] when using mineral based hydraulic oil with a viscosity of 35 mm²/s [165 SUS] and a temperature of 50°C [120°F]. For further explanation concerning how to read and use the function diagrams, please consult the paragraph "Selection of motor size" in the technical information "General" 520L0232.
