The electric motor of direct current has rotor and it consists of axis of the armature that transmits rotation to the core of the armature, windings and commutator. The core of the armature is connected to the shaft and is made of rolled steel layers, which provide a low magnetic resistance band between the poles. The blades serve to reduce the currents in the core, and the core contains axial grooves for winding placement.
The winding of the armature
is made of coils insulated from each other and from the core of the armature
and is placed in the grooves and electrically connected to the switch. The
commutator is composed of copper segments, individual insulated from each other
and the shaft, electrically connected to the coils of the armature winding.
There are four main functions of the rotor, it
allows rotation for generating action or mechanical motor action and because of
the rotation, produces the necessary action for the commutation. It contains
conductors that induce voltage or provide an electromagnetic torque and
provides a low resistance band for the flow. The stator of the DC motor
consists of housing, field winding, poles, interpolos, brushes and rings and
