TMK, TMKW and TMK 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 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].
Characteristic features of Danfoss Orbital Motors

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.
TMK can be found under Function diagrams.
•
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" DHMH.PK.100.G2.02 520L0232.

1)
This brake is to be used only as a passive parking brake. It may not be used for dynamic braking.
When release pressure2) is greater than zero, the holding torque depends inversely proportional on the
actual release pressure.
At 0 bar - holding torque = 1050 Nm [9295 lbf•in]
At 15 bar [215 psi] or more - holding torque = 0 Nm
2)
The release pressure is the difference between the pressure in the drain/brake release line and the
pressure in the vent line. The vent port must always be connected to tank.
The brake will be fully released at 15 bar [215 psi].

The drain/release port on the TMK FL motor must never remain plugged or be connected to the system A
or B pressures, since the brake is a low pressure device. A common solution for controlling the brake is to
use a two position valve to connect the drain port to hydrostatic charge pressure (brake released), or to
reservoir pressure (brake holding).
The vent port must always be connected to tank.
See the above schematic for details.
