Use as controlling motors in high-torque applications where more motors are needed, e.g. large winches. Speed control, torque control, position control, energy regeneration, safety, no load-lowering valves, system simplification, HPU downsizing. Significant system cost reduction.

​

Use as controlling motors in low speed positioning control applications (e.g. 0-25 rpm), also when only one motor is used.

Ultra fast response, precise creep mode, locking function, configurable safety.

​

Use as high power motors for continuous operation, up to 200+ rpm and up to 1.4 MW. Efficiency above 90 % in a wide working range, and high efficiency even at reduced displacement.

​

Advantages

​

• Direct supply by open circuit HPU, constant or variable pressure (motor will adapt to pressure)

• High efficiency, also at part load

• Regeneration of braking energy

• No gearbox, i.e. 4-8 % losses are removed and no backlash

• Low inertia (can be neglected in most applications)

• Fast response (50 ms to switch direction or displacement)

• Control over ethernet for easy integration in systems

• Energy efficiency comparable to electrical motor with frequency converter

• Reduced system cost
