Danfoss Energy Options has introduced the launch of its Vickers by Danfoss variable velocity drive (VSD) options throughout Europe, the Center East, and Africa.
The portfolio contains induction motor and servo motor VSD options, overlaying a broad vary of energy, dynamics, and management choices. Every system combines a hydraulic pump, electrical motor, and frequency drive with management logic, various the velocity of the electrical motor and pump to match the calls for of the obligation cycle. The modular providing is designed to go well with most industrial hydraulic functions and machine sorts, with explicit relevance in discrete and course of manufacturing.
The induction motor VSD answer options the PVM Code B axial piston pump, the Danfoss VLT AutomationDrive FC 302, and an asynchronous induction motor. Suited to methods with low dynamic and management necessities, it covers 3- to 250-kW functions, with these above 90kW engineered to order. The answer affords velocity and move on demand with open-loop management, and might scale back power consumption by 20 to 40% in contrast with conventional constant-speed architectures, relying on obligation cycle.
The servo motor VSD answer options the VGPS inner gear pump or PVMX axial piston pump — the latter at the moment engineered to order — alongside a PMSM servo motor and a Danfoss iC7-Automation drive, together with proprietary p/Q management software program for closed-loop strain and move management. Masking 3- to 100-kW functions, it’s designed for methods with excessive dynamic and management necessities. Vitality consumption reductions of 30 to 60% are claimed relying on obligation cycle, and the exact pump velocity management can allow the elimination of separate strain and move management valves, simplifying machine structure.
Each options scale back warmth technology and noise publicity. Improved power effectivity minimises warmth build-up, permitting for the downsizing or elimination of oil coolers and lengthening the service lifetime of seals and oil. Decrease working speeds additionally scale back noise for machine operators and people working close by, with potential advantages for energy unit placement and secondary noise discount necessities.
VSD methods moreover allow pump and motor downsizing by utilising the complete motor velocity vary somewhat than working at a hard and fast velocity, decreasing machine footprint and put in energy whereas reducing whole value of possession.
“The superior efficiency of Vickers by Danfoss variable velocity drive options is rooted in seamless integration. Danfoss drives are an ideal match for hydraulic VSD methods, leading to a harmonised system that’s simple to fee and function,” says Juraj Bittner, product supervisor, industrial options, Danfoss Energy Options. “By combining the sturdiness and reliability of Vickers by Danfoss pumps with the clever management of Danfoss drives, our VSD methods ship a strong, environment friendly, and cost-effective answer for contemporary hydraulic functions.”
Goal functions embody injection moulding, rubber moulding, machine instruments, presses, die casting, steel forming, and meals processing — notably the place intermittent obligation cycles imply peak energy shouldn’t be required repeatedly.
