5 General Information Orbital Motors Introduction Danfoss is a world leader within production of low speed orbital motors with high torque. We can offer more than 3 different orbital motors, categorized in types, variants and sizes (including different shaft versions). The motors size vary (rated displacement) from 8 to 8 cm 3 [.5 to 48.9 in 3 ] per revolution. Small sized motors: OML and OMM Medium sized motors: OMP, OMR and OMH OMP X and OMR X DH and DS OMEW Large sized motors: OMS, OMT and OMV TMK TMT TMTHW TMVW Speeds range up to approximate 25 min -1 (rpm) for the smallest type and up to approximate 6 min -1 (rpm) for the largest type. Maximum operating torques vary from 13 to 4 N m [115 to 35 4 lb in] (peak) and maximum outputs are from 2. to 95 kw [2.7 to 128 hp]. Wide range of Danfoss orbital motors Danfoss January 218 BC388en-US21 5

7 General Information Orbital Motors Literature Overview general catalog of all Orbital Motors with technical data gives a quick motor reference based on: selection of orbital motor, function in hydraulic systems, power, torque, speed and capabilities. More detailed information can be found in an individual motor catalogs. Literature title Literature type Reference number Orbital Motors in General Technical Information BC83 OML and OMM Orbital Motors Technical Information BC87 OMP, OMR and OMH Orbital Motors Technical Information BC84 OMS, OMT and OMV Orbital Motors Technical Information BC9 DH and DS Orbital Motors Technical Information BC92 OMEW Orbital Motors Technical Information BC62 TMK, TMKW, TMK FL Orbital Motors Technical Information BC98 TMT, TMTU, TMTW, TMT FL Orbital Motors Technical Information BC12 TMTHW Orbital Motors Technical Information BC23 Operating Parameters Diagrams The 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 diagram for each motor size. 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 1 bar [75 and 15 psi] when using mineral based hydraulic oil with a viscosity of 35 mm 2 /s [165 SUS] and a temperature of 5 C [12 F].

These bearings and the recessed mounting flange allow a higher permissible radial load in comparison to OMP X motors. The permissible radial load on the shaft is shown for different speeds as a function of the distance from the mounting flange to the point of load application. Curve indicates the max. radial shaft load. ny shaft load exceeding the values quoted in curve will involve risk of breakage. The other curves apply to a B 1 bearing life of 2 hours at the number of revolutions indicated by the curve letter. Mineral based hydraulic oil with a sufficient content of anti-wear additives must be used.

The permissible higher radial load is therefore due to the recessed mounting flange moving the point of load closer to the motor bearings. The permissible radial load on the shaft is shown for different speeds as a function of the distance from the mounting flange to the point of load application. The curves are not based on calculations of B1 bearing life. They represent absolute limits that must not be exceeded.
