what will be happened when a single phase motor is supplied
by the dc supply
Answer Posted / tathagata
If single phase motor is supplied by ac supply, it will rotet
because single phase motor are universal motor. So it work
for both AC & DC.
But the DC supply must be less than its AC rating, because
in DC there is no reactant .
I=V/(R+jX) (AC)
I=V/R (DC)
So current is vary high which may burnt out the winding.
