Multi-Stroke Cam-Lobe Motors & Wheel Motors

Modular cam-lobe motors, 160–15,000 cm³/rev, with brake and two-speed options

Multi-stroke radial piston motors in which each piston works several times per revolution against a lobed cam ring, giving very high torque in a short, compact housing. They are supplied as shaft motors or as wheel motors with a studded hub, rated at 21–25 MPa with maximum pressures up to 45 MPa and up to 95,400 N·m maximum torque. Modular construction allows a spring-applied parking brake, two-speed (dual displacement) valving and speed-sensor preparation to be added.

Typical specifications

Displacement: 160 – 15,000 cm³/rev
Max. torque: 1,018 – 95,400 N·m at max. pressure (rated 635 – 59,825 N·m at 25 MPa)
Pressure (rated / max.): 21 – 25 MPa rated; max. 25 – 45 MPa (type-dependent)
Speed range: 0 – 670 r/min (size-dependent)
Max. power: 18 – 240 kW
Weight: 20 – 475 kg without brake; brake module 4.4 – 98 kg

Ranges across the product family. Exact figures depend on the model.
