Technical Information TMTHW 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].
•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
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:

Technical Information TMTHW Orbital Motors
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:
Leading performance with a long lifetime makes light work of the heaviest duties. Offering pressure capability up to 350 bar [5076 psi] and high starting torque, the T-Series is the energy-efficient choice for the toughest working environments.
The O-Series is flexible beyond compare. Delivering premium power across the board, these motors cover small to large, medium to heavy-duty needs with pressure capability up to 275 bar [3990 psi]. Robust, reliable and designed to fulfill the latest emissions standards.
The V-Series is your quality benchmark in the medium duty market. Based on proven technology, these reliable motors will reduce your overall system costs while adding value to your machine. Perfect for many tasks.
•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
