How Does a Dynamo Generate Electricity for Charging Applications?
A dynamo generates electricity for charging applications through a straightforward process of electromagnetic induction. First, it consists of magnets and a coil of wire. When the dynamo’s rotor spins, it creates relative motion between the magnets and the coil. This motion induces an electric current within the coil due to electromagnetic principles.
Next, the alternating current (AC) produced in the coil flows through electrical circuits. Many charging applications require direct current (DC), so a rectifier converts the AC into DC. This conversion allows the generated electricity to be compatible with various batteries, including those in e-bikes and USB chargers.
Furthermore, the dynamo’s output current can vary based on its rotation speed. This means that consistent speed during pedaling or movement maximizes electricity generation. As a result, the stored energy in batteries increases efficiently.
