The magnetic materials of the motor cores must have high induction of saturation, thus ensuring that the motor operates at a high magnetic flux point, 3 horsepower 182TC frame always below the saturation point. The space reserved for the coils is called a groove, and the structures that will form the poles themselves are the teeth. In the stator winding, copper coils are coiled around the stator teeth, and these windings can be three-phase or single-phase in the induction motors.

The coils are insulated from each other by a lacquer coating, insulated from the groove, tied with an insulated string and coated with an additional layer of lacquer. They are organized so that the ligament of the three phases can be made in star, triangle or other tensions. The magnetic core is responsible for adding the magnetic field flux caused by the coils and thereby forming electromagnets at their poles. In direct current electric motors, these poles are fixed, whereas in alternating current motors the field generated is the rotating field. The stator is coiled with several thin blades of magnetic material, pressed together to form the stator assembly.
