How ti wind the stator of an ac machine
Any generator that rotates will naturally generate AC power into the stationary winding. Wind generators are (all I believe, but could be wrong) induction machines, meaning an AC source is applied to the field and an AC output is generated in the stator. Just like an induction motor, the machine operates with some slip (the rotor speed + the field power frequency = the stator power frequency). If the machine is turning above synchronous speed (so the slip is negative in my equation), the machine will be generating power instead of using it.
AC motor has two main winding components - stator and a rotor. Stator winding is stationary where as rotor winding is on rotating part.
AC generator is a rotating machine with a rotor and stator winding, driven by another prime mover, which generates alternating current at a specified voltage.
The 'stator' is the generic term for the stationary parts of a machine, including its frame, magnetic circuit, poles, windings, etc.
why the supply is given to the stator of dc generator give answer
The number of poles on stator and rotor is always the same. If they are not equal?æno torque will be produced, thus, the machine will not function.?æ
a ROTOR is basically any part of a machine that rotates. eg the armature in a motor a STATOR is the part of a machine that is stationary. ie the ROTOR revolves within the STATOR
The stator and the magnets.

Only Stator winding is similar in both the cases.
Yes, AC voltage.The regulator makes it DC.
An AC generator (Alternator). A rotor is turned into a magnet by what is known as 'excitation' current. The rotor then induces AC current in the stator windings as it is rotated within it. This is AC, due to the fact that the rotor has a north and south pole, which alternately induces current in the stator windings. The exitation current is provided to the rotor via slip rings. Controlling this excitation current will also control the output power by suitable control circuitry. This is the same principle, whether it is a small domestic generator, a power station, a wind turbine, or a car alternator.
