Product Overview
The 3V Mini DC Motor is a compact brushed DC motor designed for low-voltage applications such as educational electronics, robotics prototypes, and hobby projects.
This motor converts electrical energy into rotational mechanical motion, making it suitable for driving wheels, fans, propellers, and small mechanical systems.
Thanks to its simple construction, low power consumption, and high rotational speed, this motor is widely used in STEM education kits, Arduino experiments, science projects, and DIY robotics.
These motors typically operate from 1.5V to 3V DC and can reach speeds up to approximately 10,000–12,000 RPM without load, depending on the supplied voltage.
