Perfect for your next DIY or science project! This is a small N20-style gear motor that runs on 3 to 12 volts DC. At 12V, it spins at about 15 RPM (nice and slow, good for torque). The kit includes the motor itself, a metal mounting bracket (fixed frame), a large plastic wheel (about 43mm in diameter), and some screws and nuts to put it all together. The motor shaft is 3mm, and the wheel has a matching hole. You'll need to provide your own power source (battery pack, solar cell, etc.) and wires. It's intended for builders, hobbyists, or students – you get the parts, you figure out how to use them! Great for making simple robots, moving displays, mini cars, or other kinetic projects. It's a basic, affordable way to add motion to your creations. Just solder on some wires, hook up power, and watch it go!
