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].

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.

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.
