A dynamo is an electrical generator that utilizes a commutator to generate direct current.
Dynamo is a device that converts mechanical energy into electrical energy.
Dynamos were the first electrical generators utilized just to supply power to industry, as well as they served as the platform for several subsequent electric-power conversion types of equipment, such as the alternating-current (AC) alternator, electric motor, as well as a rotary converter.
Working of Dynamo:
The image below shows a basic dynamo with such a coil constructed of conducting wires that are positioned between the North pole and South pole of two permanent magnets.
Whenever the coil is to be motionless, no voltage is produced. The magnetic field changes as the coil spins, causing a voltage to be generated within the coil.
3. The left side of the coil travels from the North pole of such a left magnet during the first half of the revolution. The coil travels from the South pole of the right magnet throughout the second part of the revolution.
There are two conceivable polarities throughout these rounds:
An alternating voltage is a difference between their polarities.
