B1625 DC 5V 38RPM Mini Planetary Gear Motor - 16mm Brushless For DIY Robot & Arduino

About This Product

DIY electronics and robotics folks, check out this cool little motor! It's a B1625S model brushless DC motor that runs on 5V and delivers 38 RPM through its built-in planetary gearbox. The 16mm diameter makes it compact enough for small projects, and the 4mm shaft (with 2.4mm flat) connects easily to wheels, gears, or other components. This is a used unit that's been sitting in a warehouse but tested as working perfectly - so you get functionality at a lower price. It's unbranded/generic from China, perfect for Arduino projects, Raspberry Pi robots, small vehicles, model builds, or any application where you need reliable, low-speed torque. The planetary gearbox reduces the motor's natural high speed to a usable 38 RPM with increased torque - great for moving things without straining the motor. Whether you're building a line-following robot, a mini sumo bot, an automated display, or just learning about motor control, this little workhorse delivers. Note it's used but functional, so expect possible cosmetic imperfections from storage. No UPC, but for hobby projects where exact specs matter less than functionality, this motor offers great value. Get those creative projects moving - literally!
