what is rotatng magnetic field in case of three or multiple
phase alternating current machines???



what is rotatng magnetic field in case of three or multiple phase alternating current machines???..

Answer / rajesh

when a 3 phase supply is passed into stator . the plot of
voltage vs time will give rise to resultant voltage .
this is then converted to magnetic field due to faradays law
. when u plot again u will get the resultant current . The
rotating magnetic field ( also magnetizing magnetic field )
has voltage current char similar to 3 phase supply . the rmf
is hypothetical concept to link field between stator and rotor
