DC motors are compact machines with excellent dynamic properties, which meet the most different applications in the areas of process control. They are classified according to the type of connection of their fields, such as the permanent magnet motor, which is characterized by being a small power motor, very applied in the toy industry, the automotive industry and many other industrial applications.
According to the voltage variation of the terminals will be the speed variation. The armature that is the rotating part of the machine is composed of an axis, and of a core of the armature made of steel plates with grooves, where the coils are located (winding of the armature) and a switch fixed on the shaft. The DC electric motor supports high currents.
The stator is responsible for the magnetic field that interacts with the armature, and is even mounted around it and is the static part of the machine.
The housing is formed by plates where the field winding is fixed. The brushes conduct energy from the commutator to the rotor and the coils are that form the poles.
