It is common knowledge that the primary function of the universal electric motor is to make the electrical energy is transformed into mechanical energy of rotation.
The main parts of a universal electric motor are: armature or rotor; switch; field winding or stator; brushes.
The armature or rotor function in electric motor is receiving current from a power source that is outside and make armor and turn this function, the armor also receives the rotor name.
All electric motor has a commutator, since the main function of it is to make the alternating current pass through the armor LEESON M1740008.00. The constitution of the switch features: curved copper plates fixed and which are placed on the armature shaft.
The field winding or the stator act within the electric motor and causes the magneto-motive force is produced in a certain amount so that the generation of the magnetic flux occurs.
The electric motor brushes are fixed graphite connectors that are under the springs and this causes them to brush the switch.
