How does an Electric Motor work? (DC Motor)

The video tutorial explains the components and functioning of a basic DC motor. It covers the motor's protective casing, shaft, rotor, and the role of magnets in creating a magnetic field. The commutator and brushes are discussed in detail, highlighting their role in completing the circuit and enabling rotation. The video also addresses the impact of Eddy currents on motor efficiency and how laminated disks help reduce these currents. Finally, it explains the flow of electricity through the motor and the effects of arcing on the brushes.

Explain the significance of using laminated disks in the rotor.

What happens to the efficiency of the motor if large Eddy currents are present?
