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 3,000 different orbital motors, categorised in types, variants and sizes (including different shaft

Technical Information
TMTHW Orbital Motors
Introduction the Orbital Motor Series
By introducing the TMTHW, Danfoss is introducing the first Orbital Motor of a new 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.
TMTHW features
Robust bearing design
•
Not sensitive towards return pressure
•
Extra patented sealing design
•
High pressure rating
•
Excellent performance / weight
•
Designed based on decades of experience with orbital motor-technology

Technical Information
TMTHW Orbital Motors
Speed, torque and output
The following 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 diagrams on page 12.
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.

The output shaft runs in tapered roller bearings that permit high axial and radial forces.
The permissible radial load on the shaft is shown for an axial load of 0 N as a function of the distance from
the mounting flange to the point of load application.
The curve is based on B10 Bearing life (2000 hours or 12 000 000 shaft revolutions at 100 min 1) at rated
output torque, when mineral-based hydraulic oil with a sufficient content of anti-wear additives, is used.
