Abstract
It is believed that electric motors consume 64% of industrial electricity demand. When commercial use is included the total cost of motive power to UK business is over Pound 3,000M. Currently available technologies could save over Pound 300M in installations with payback periods of two years or less. This report provides potential users with information on the types of drives now available and the applications to which they are most suited. In recognition of the potential savings opportunities the University of Surrey Industrial Electronics Group was commissioned to perform efficiency tests on a range of VSD systems. Three types of drive were tested on a fan type load. These drives - PWM Inverter, Eddy Current Coupling and Switched Reluctance Drive - were tested at 7.5 kW and 22 kW. Only the PWM Inverter was tested at 45 kW. Tests on the PWM Inverter were performed with a standard and a high efficiency motor at all three ratings. (author)
