Web7 jan. 2024 · First, let’s look at a typical VFD powering an AC induction motor. Three-phase AC induction motors, which have been in use for more than 100 years, are fixed-speed devices when powered directly from the AC line. The motor speed is determined by its number of poles and the frequency of its supply, which here in the U.S. is 60 Hertz. WebThe efficiency of both standard and energy-efficient motors typically peaks near 75% of full load and is relatively flat down to the 50% load point. Motors in the larger size ranges can operate with reasonably high efficiency at loads down to 25% of rated load.
