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].
