Cutting the energy use of electric motors

05 December, 2004

Savings of up to 20% in the electricity used by motors in ventilation and air-conditioning plant are claimed by SavaWatt using Savacontrol. Energy is saved in two ways. By intelligent switching of the motor a hundred times a second, the input power is matched to actual power requirement at anything less than full load. A second form of energy saving improves the part-load efficiency of motors, which also reduces operating temperature and prolongs the motor’s life. SavaWatt says that for users of equipment with one compressor, Savacontrol offers the best solution to reducing energy use.
