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
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 approximate 2,500 min-1 (rpm) for the smallest type and up to approximate 600 min-1
(rpm) for the largest type.
Maximum operating torques vary from 13 N•m [115 lbf•in] to 2,700 N•m [24,000 lbf•in] (peak) and
maximum outputs are from 2.0 kW [2.7 hp] to 70 kW [95 hp].
The Danfoss Orbital Motors are used in the following application areas:
• Construction equipment
• Agricultural equipment
• Material handling & Lifting equipment
• Forestry equipment
• Lawn and turf equipment
• Special purpose
• Machine tools and stationary equipment
• Marine equipment
A general survey brochure on Danfoss Orbital Motors gives a quick motor reference based on power,
torque, speed and capabilities.
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:
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
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.
