Magnetically Coupled Adjustable Speed Motor Drives - Motor Tip Sheet #13

Program Document ·
OSTI ID:1216460
Alternating current electric motors rotate at a nearly constant speed that is determined by motor design and line frequency. Energy savings of 50% or more may be available when fixed speed systems are modified to allow the motor speed to match variable load requirements of a centrifugal fan or pump.
