Question

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

Answer 1

1) Armature- Rotates when electric current is passed hence its kinetic energy can be used for various purposes.

2) Brushes- Maintains contact of the armature coil with the main circuit while rotating.

3) Split Rings- Prevents the rotation of the main circuit while the rotation of armature coil.
