Need a reliable little motor for a DIY project? This Hyuduo 25mm DC gear motor might be just the thing. It runs on 12V DC power and puts out about 500 RPM (revolutions per minute) at that voltage. It's a 'low speed, high torque' type thanks to its internal metal gears, which are way more durable than plastic ones. The body is about 25mm (1 inch) in diameter, with a 3mm shaft that's 10mm long. It's rated for 3.5 watts of power. People use these in all sorts of stuff: electronic door locks, smart cars or toy cars, robotic arms, small robots, elevator models, and other electronic toys or gadgets. It's a brushed motor, so it's straightforward to wire up. Just pick the RPM you need from their options (they have from 5 RPM all the way up to 1000 RPM). Comes with one motor. Good for hobbyists, tinkerers, or repair jobs where you need a compact, powerful little driver.
