In electric motors, a stator is a group of cylindrical windings that will produce an electromagnetic field. The stator is comprised of a housing, a core, windings and bearing sleeve. The stator housing is the largest source of mechanical power of the entire motor. It will support the stator core,  providing support for the rotor and shaft, and is the normal point of attachment between the motor and its base. The stator core is made of a large amount of fine silicon steel laminations in which the stator windings are wound. A lamination is a thin sheet of steel. The stator core strengthens the magnetic field caused by stator windings.

The stator windings are coils of insulated wire through which the current can pass. The stator windings create the rotating electromagnetic fields to which the rotor counterposes. The coils are connected and formed to suit the specific dimensions of the stator and respective stator poles. The bearing sleeves are metal plates that are on each end of the engine. The bearing sleeve houses the shaft bearings and holds the rotor in the correct position inside the stator.
