Electric Motor
It converts electrical energy into mechanical energy.
Principle of Electric Motor
The principle of the electric motor is based on the fact that a current carrying conductor produces a magnetic field around it. A current carrying conductor placed perpendicular to magnetic field experiences a force.
Construction of Electric Motor
(1) Armature coil: It consist of a single loop of an insulated copper wire in the form of a rectangle.
(2) Strong field magnet: Armature coil is placed between 2 pole pieces of a strong magnet which provide strong magnetic field.
(3) Split ring type commutator: It consist of 2 halves of a metallic ring.The two ends of armature coil are connected to these 2 halves of ring.Commutators reverses the direction of current in armature coil.
(4) Brushes: Two carbon brushes press against the commutator.These brushes act as contact between commutator and terminal battery.
(5) Battery: It is connected across the carbon brushes.It supplies current to the armature coil.
