Overview
A Dynamo Motor and Generator is a dual-function device that can operate as:
A DC motor, converting electrical energy into mechanical motion.
A generator, converting mechanical motion into electrical energy.
This makes it ideal for STEM education, physics experiments, and electronics projects that teach electromagnetism, energy conversion, and motor principles.
Key Features
Dual Function: Works as a DC motor and a generator
Voltage Range: Typically 3–12 V for motor operation
Output Voltage: Generator output depends on RPM and load (usually 0–6 V)
Compact Size: Fits easily on breadboards or STEM kits
Hands-On STEM Learning: Demonstrates Faraday’s Law of Electromagnetic Induction
Suitable for Arduino or simple circuit experiments
