Motor & Drive Control
Your motors run flat out when the process only needs part of the flow
A pump throttled against a valve, a fan damped down, a conveyor slamming to full speed on every start, all of it burns energy and wears out the mechanical end of the system. The fix is speed matched to demand, and a drive specified against the whole electrical chain rather than picked off a power rating.
The Four Loads That Drive Most of the Saving
Where speed control pays back fastest, and the question that decides how it should be controlled.
Pumps
Throttling against a valve wastes most of the energy the motor draws. Speed control matches flow to demand and takes the pressure spikes out of the system.
Fans & Blowers
Variable-torque loads where a small speed reduction returns a large power reduction, usually the fastest payback on site.
Conveyors & Materials Handling
Controlled ramps stop belt slip and gearbox shock loading, and let multiple drives share load along a long run.
Compressors & Process Machinery
High-inertia and constant-torque duty where inrush, restart limits and thermal duty decide the topology, not just the kW.
Three Ways to Start and Control a Motor
Not every motor needs a drive. Choosing the cheapest adequate method is part of the specification.
Sizing is only half of it. Cable length, motor insulation, harmonic exposure and braking duty decide whether the drive needs filtering, a brake chopper or a different topology altogether, nine checks we run before quoting.
What Sites Get Out of It
The outcomes that matter on site.
Energy Drawn to Match Demand
Variable-torque loads follow the affinity laws, modest speed reductions on pumps and fans cut power draw sharply.
Less Mechanical Wear, Fewer Stoppages
Ramped starts protect belts, couplings and gearboxes from the shock loading that shortens their life.
Tighter Process Control
Closed-loop speed on pressure, flow or level holds the setpoint instead of hunting between on and off.
Compliance and Safety Built In
Safe Torque Off to SIL3, harmonic mitigation and EMC filtering specified against your site requirements.
Danfoss, a drive tier for every duty, from OEM panel to liquid-cooled
We are an authorised Danfoss drive partner supplying the full VLT, VACON and iC range, plus the VLT MCD soft starter family and line-side and output filtering. One brand across every tier means the control philosophy, fieldbus and spares strategy stay consistent as the site grows.
