VFD and motor control

Speed control for conveyors, pumps, fans and mixers. Frequency inverters save energy, start motors smoothly and let you set the speed exactly.

Power needed by a fan or centrifugal pump at reduced speed Theoretical power at 100, 90, 80, 70 and 60 percent speed: 100 percent, 73 percent, 51 percent, 34 percent, 22 percent of full power. 100%100%73%90%51%80%34%70%22%60% Motor speed Power needed
At 80% speed, a fan or centrifugal pump needs only about half the power (theoretical).

What you get

Drives that are sized, wired, set up and connected to your control system.

  • Drive sizingInverter and motor selected for your load and duty.
  • Panel design and buildInverters with protection, filters and cooling in the panel.
  • Parameter setupRamps, speeds, limits and protections set for your application.
  • Network integrationControl and monitoring from your PLC over the network.
  • CommissioningStart-up on site, with service afterwards.

Why variable speed saves energy

On fans and centrifugal pumps, the power needed falls with the cube of the speed. Running at 80% speed needs only about half the power.

  • Lower energy useMatch the speed to the real demand instead of throttling.
  • Smooth starts and stopsLess mechanical stress on belts, gearboxes and products.
  • Better process controlSpeed set exactly from the PLC or operator panel.

Chart values are theoretical for fans and centrifugal pumps. Actual savings depend on the system.

From design to a running machine

One team handles the whole panel.

  1. DesignElectrical schematics, component selection and panel layout.
  2. BuildAssembly and wiring of the panel in our workshop.
  3. ProgramInverter parameters and PLC communication set up for your machine.
  4. CommissionInstallation, start-up and training on site, with service afterwards.
