1) Explain construction and working of DC motor with neat labelled diagram.
Answers
Explanation:
A d.c. motor consists of : 1. Rectangular coil ABCD of insulated copper wire moved between two Horse shoe 2. Permanent magnet M such that AB and CD are perpendicular to the magnetic field. 3. Two half rings (commutators) of copper X, Y are soldered to ends A and D of coil to change the direction of current flowing after every half rotation of the coil. 4. Two carbon brushes P and Q fixed to the base of motor keep pressing highly against commutators. Battery to supply the current to coil is connected to the coil. The function of brushes is to make contact with the rotating rings of the commutator and through them to supply current to the coil.Read more on Sarthaks.com - https://www.sarthaks.com/273960/a-draw-a-neat-and-labelled-diagram-of-a-d-c-motor-and-explain-its-construction-and-working
