Explain the function of the following parts of an electric motor.
(i) Armature
(ii) Brushes
(iii) Split ring

(i) Armature: It contains of a single loop of inculated copper wire in the form of a rectangle.

(ii) E rushes: Two carbon brushes B1 and B2 press against the commutator. These brushes act as the contacts between the commutator and the terminals of the battery.

(iii) Split-ring: It consists of-two halves (R1 and R2) of a metallic ring. The two ends of the armature coil are connected to these two halved of the ring. Commutator reverses the direction of current in the armature coil.
