Low-Cost Inverters for Pump and Fan Drives

In a paper originally presented at the First International ConferenceEnergy Efficiency Improvements in Electric Motors and Drives[1], Prof T de Almeida examined the potential for energy savings in the European Union by the use of high-efficiency motors and/or drives. His data clearly showed that whilst the energy savings that may be obtained by switching to EEMs are significant, they are not as large as those that may be achieved if VSDs are adopted.
