Danfoss VFDsAdvantages of infinitely variable Speed adjustment
Today, the frequency converter controlled, three-phase AC Motor is a standard element in all automated process plants. Apart from its ability to use the good properties of three-phase AC motors, infinitely variable speed regulation is often a basic Requirement because of the design of the plant. In addition, it offers a number of further advantages:Energy savings
Energy can be saved if the motor speed matches requirements at any given moment in time. This applies in particular to centrifugal pumps and fan drives where the energy consumed is reduced by the cube of the speed. A drive running at half speed thus only takes 12.5% of the rated power.
Process optimization
Adjusting the speed to the production process offers a number of advantages. These include increasing production, while reducing rejection rates and decreasing energy consumption and wear.
Smooth machine operation
The number of starts and stops with full speed change can be dramatically reduced. Using a VFD will eliminate stop ramps, shocks and impacts on the machine.
The Car Washing Industry can take advantage of all the cost savings and wear that their current car wash controller can not deliver. Hydraulic Power Packs, High Pressure Pumps and Blower Motors can all take advantage of the use of Variable Frequency Drives by Danfoss.
