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.
