1st Quarter 2019Electrical switching & drive systems & components
Operating an irrigation system can be expensive, with one of the primary factors being the cost of energy. However, significant savings can be realised by leveraging available technology to provide an appropriate electric motor and variable speed drive combination that will reduce operating costs while providing reliable performance. WEG IE3 top premium efficiency motors and variable speed drives (VSDs) from Zest WEG will do just that.
For example in a pivot pump application which operates for 4000 hours in a single year – relative to two planting cycles – WEG IE3 top premium efficiency motors not only offer maximum ingress protection with a higher winding insulation system to increase motor life expectancy, but also offer efficiencies of up to 96,6%. Benefits can also be seen when compared against IE1 standard efficiency motors. Using a 22 kW 2 pole at 75% of full load, an IE1 motor with an efficiency of 91%, measured against a WEG IE3 motor with 93% efficiency, has estimated savings of R2100 per year.
Much higher savings can also be realised by using a WEG VSD in combination with a WEG motor. An IE1 electric motor, again operating for 4000 hours per year at 91% efficiency, will consume about R93 800 worth of energy using old technology. The same performance could be achieved using a VSD to reduce the motor speed while reducing the energy absorbed. For a 10% reduction in operational speed using the VSD, further savings of 22% to 27% could be achieved.
