The stator is not laminated in DC machines because it does not need to be laminated.
Lamination is used in AC machines to prevent eddy currents from generating excess power due to the transformer effect of having a one-turn secondary that is short circuited. There is more to it than just the laminations - the laminations are insulated from each other, and interleaved, so that they have poor electrical connection while having good magnetic coupling.

Hetropolar field winding in dc machines?
a common magnetic flux crosses the air gab from stator to rotor cores causing in the production of north and south poles in the air gab between them
Is it possible to run a DC brushless motor without an electronic driver?
No. In a "regular" DC motor, the permanent magnets form the stator, and the brushes and commutator are used to get the DC to the rotor windings. In a brushless DC motor, the magnet is the rotor, and the stator is a group of coils arranged in a circle to form the stator. The electronic controller drives the individual coils in the stator. There isn't a good way to drive them without an electronic controller. A link is provided to the Wikipedia article on the brushless DC motor (BLDC). At least surf on over and check out the pics. The ones showing motors that have been taken apart are particularly helpful.
How rotar rotates of DC motor?
The rotor in a DC motor rotates because the magnetic field in either the rotor or the stator is constantly changing. If it is a brush type DC motor, then the rotor field changes as the rotor moves to a new position on the commutator. If it is a brush-less type DC motor, then there is some circuitry associated with the stator that changes the stator field.
How many types of DC machine?
05 types of dc machines
Why DC motors and DC generators are commonly known as DC machines?
because the dc motor will act as dc generator as same as dc generator acts as a dc motor .so it is called as dc machines.AnswerBecause generators and motors are machines, and operate on d.c.'A.C. machines' are generators, transformers, and motors which operate on a.c.
What will happen of you give AC supply to stator winding of DC generator?
why the supply is given to the stator of dc generator give answer
Why are stator cores laminated?
Thin metal laminations are used to minimize the magnetic flux eddy current loss in the stator cores of high-speed, high-performance induction motors.
Hetropolar field winding in dc machines?
a common magnetic flux crosses the air gab from stator to rotor cores causing in the production of north and south poles in the air gab between them
What does stator dose on an alternator?
The stator windings produce current when the rotor spins its magnetized head within the stator windings. The current is dc and is changed into ac and back into usable dc current. This is so you don't get lights flaring associated with the generators of the old days.
In a dc motor the input power is given to stator or rotor?
rotor
What is mechanical loss in dc machines?
Friction and windage causes mechanical loss in DC machines.
What is the function of exciter rotor and stator in Generator Operation?
In the operation of a standard generator, the exciter rotor and stator provide DC-type energy to an AC-type supply. This allows the exciter to maintain a constant DC source.

How do you chech the stator on a 1991 FLHTC When I unplug the regulator from the stator I should be able to take a volt meter and with the engine running get a volt reading from the stator. Right?
Yes, AC voltage.The regulator makes it DC.
What is the principles of DC machines?
All DC machines are works based on the principle of FARADAY'S LAW OF ELECTROMAGNETIC INDUCTION.
