20 Pack Mini DC Generator Motors - 3V-12V For DIY Wind Turbine & Science Projects

About This Product

Calling all makers, students, and DIY enthusiasts! This 20-pack of mini generator motors is perfect for all your science projects and creative builds. These little silver motors run on 3V to 12V DC power and can hit speeds from 1,500 to 6,500 RPM depending on the voltage you feed them. Each motor measures about 0.94 inches in diameter and 0.87 inches tall, with an 0.32-inch shaft - perfect for attaching to small gears, propellers, or whatever your project needs. The 14cm wires give you plenty of length to work with for connections. What's really cool is how versatile these are - use them to build miniature wind turbines, hand-crank generators, small fans, or any other physics experiments you can dream up. They work great with batteries or solar cells, making them ideal for renewable energy demonstrations. Just a heads up - these have small parts, so they're not for kids under 3 years old. When you're not using them, store them in a sealed bag to prevent rust and keep them in good condition. Whether you're a teacher stocking up for classroom projects, a parent looking for STEM activities, or a hobbyist working on your next creation, having a bunch of these on hand is super convenient. The quality is solid for the price, and having 20 means you can experiment freely without worrying about burning one out. Seriously, if you love tinkering with electronics or need reliable motors for educational purposes, this pack is an absolute steal and will keep you busy for ages!
