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

I have a relay contact rated at 220v dc which is supplied with a 24vdc from the panel,for it to trip the dampers(24vdc).What if the application of the relay changes so that it should work at its rated 220vdc then will it work at 24vdc supply given or any other consideration needs to be taken .....
