The 4V–12V Dynamo Motor Generator is a compact DC motor that can also be used as a small generator. When mechanical force is applied to the shaft, it can produce electrical output. It is suitable for DIY generators, hand-crank projects, science experiments, and small renewable-energy projects.

Features

• Works as both a DC motor and generator
• Wide operating range of approximately 4V–12V
• Metal body for durability
• Compact and easy to mount
• Smooth rotating shaft
• Suitable for low-power generation experiments
• Easy to integrate into DIY projects

Specifications

Note

The generator’s actual voltage and current output depend on shaft speed, mechanical load, and motor characteristics. Do not assume a constant 12V output. When using it for battery charging or powering sensitive electronics, use an appropriate rectifier, voltage regulator, and current-limiting circuit.
