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-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].
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:
•Motors with corrosion resistant parts

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.

1)Brakes with higher holding torque available, please contact Danfoss.
2)The release pressure is the difference between the pressure in the brake line and the pressure in the drain line.
Bleed off from brake release chamber to drain line is 0.65 l/min [0.172 US gal/min] at 13 bar [188 psi] release pressure.
Maximal permissible shaft seal pressure
TMT with standard shaft seal and drain connection.
The pressure on shaft seal equals the pressure in the drain line.
TMT FL and TMTW FL with standard shaft seal.
The pressure on shaft seal equals the pressure in release port.

Permissible radial shaft load
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 Information
TMT, TMTU, TMTW, TMT FL and TMTW FL Orbital Motors
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.
