What is RMF? RMF stands for Rotating Magnetic Field and in case of a 3-Phase supply system whenever the 3-phase windings(R/Y/B) are physically displaced by 120 degrees along the periphery and are electrically being fed from a 3 –phase supply which are time-displaced by 120 degrees electrically. Then we have three mmf (Magneto Motive Force) […]
