Technical Information
TMT, TMTU, TMTW, TMT FL and TMTW FL Orbital Motors
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
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
(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].
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)
•

Data survey
Speed and torque
Peak values, Intermittend values, Continuous values
The bar diagrams above 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 for each motor size.
TMT can be found in Function diagrams on page 17
•
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.

Permissible radial shaft load
TMT FL
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.

Technical data
The curve is based on B10 Bearing life (2,000 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.
The dash curve A shows max. radial shaft load. Any shaft load exceeding the values shown in the curve
will involve a risk of breakage.
