DC 12V 300RPM Micro Speed Reduction Gear Motor COM41 ,R16

DescriptionDesigning compact hardware often means making difficult compromises between physical size, power requirements, and mechanical strength. The 12V 300RPM N20 Micro Metal Gear Motor completely eliminates this trade-off. This microscopic motor is an engineering marvel, widely recognized in the maker community for delivering astonishing torque and pulling power despite being small enough to rest on the tip of your finger.The 12V AdvantageMany robotics and automation projects run on 12V power supplies (such as 3S LiPo batteries or 12V wall adapters) to power larger components or long LED strips. Standard N20 motors are typically rated for 6V, meaning you would have to install a bulky buck converter to safely power them. This specific N20 motor features internal windings specifically rated for 12V DC, allowing you to run it directly from your main 12V motor driver without the risk of burning out the coils.The All-Metal Mechanical Advantage (300 RPM)Unlike cheap toy motors that rely on fragile plastic gears, the N20 features an exposed, all-metal reduction gearbox stacked directly onto the front plate. The gearing reduces the high internal speed down to 300 RPM (exactly 5 rotations per second). This is considered the “sweet spot” for small robotics, offering a perfect balance between a brisk driving speed and high pushing torque. The hardened gears can withstand significant mechanical stress, and the solid brass mounting plates keep the gears perfectly aligned.Standardized 3mm D-ShaftDespite its tiny stature, the motor outputs its power through a highly standard 3mm “D-shaft.” The flattened side of this stainless steel shaft guarantees that custom 3D-printed hubs, miniature rubber wheels, and tiny metal pinions will lock securely in place without slipping under a heavy load.Driving the N20 MotorBecause this is a standard brushed DC motor, you can drive it using standard hardware. It pairs beautifully with micro-sized dual H-bridge motor drivers like the DRV8833 or the TB6612FNG (ensure your driver is rated to handle 12V on the motor supply pins). By using simple PWM signals from your Arduino or ESP32, you can achieve precise forward, reverse, and variable speed control.Key Features:Native 12V Operation: Eliminates the need for step-down voltage regulators in 12V hardware builds.Ultra-Compact Footprint: Fits into the smallest 3D-printed enclosures and robotic chassis designs.Exceptional Torque-to-Size Ratio: The metal gearing allows this tiny motor to push, pull, and lift loads far beyond what its size suggests.Technical Specifications:Motor Size / Model: N20Operating Voltage: 12V DCOutput Speed (No Load): 300 RPMGear Material: Steel / BrassShaft Diameter: 3mm (D-Shaft)Shaft Length: ~9mm to 10mmOverall Dimensions: ~12mm x 10mm x 36mm (including shaft)Ideal Applications:Driving 12V 3D-printed robotic arms and micro-grippersActuating deadbolts in custom DIY 12V smart home locksDesigning motorized camera gimbals and miniature pan/tilt mechanismsExtrusion drives in small-scale 3D printers and 3D pens
