Coreless Micro DC Motor 8x16mm 3.7V

Power your next micro build with this compact 8x16mm coreless DC motor, purpose-built for tiny aerial and robotics projects that demand a strong power-to-weight ratio. Unlike conventional iron-core motors, the coreless winding design eliminates cogging and delivers instant acceleration, smooth rotation, and low current draw, making it a favorite among micro drone builders, quadcopter hobbyists, and DIY robotics enthusiasts. Running on a single-cell 3.7V LiPo or Li-ion battery, this motor spins up to 50,000 RPM straight out of the box, giving small quadcopters and toy drones the thrust they need with minimal weight penalty. Its lightweight, brushed construction means simple two-wire control — no ESC or complex commutation circuitry required, just a basic PWM signal or direct voltage drive from a MOSFET or H-bridge. The short 0.8mm output shaft accepts micro propellers or gears directly, and reversing the two leads reverses rotation direction, giving builders flexibility during assembly. Whether you’re repairing a mini drone, building a palm-sized quadcopter from scratch, or experimenting with micro robotics, this motor offers an excellent balance of speed, efficiency, and compact size for projects where every gram counts.
