Question { Areva, 10115 }

what will happen ac motor give to dc supply

Answer

AC motor works on the principle of induction..
The windings in the ac machine are wound either is delta or
star wound. ( ac machine windings )
Only if there is a rotating magnetic field we have an emf
being induced and hence the current.
So only when these current carrying conductors are placed in
the magnetic field, there is a torque!

So if we give a dc supply.. no emf hence no current and
hence no motion! Its in stand still position!
