12V DC 300 RPM High Torque Gear-Bo Motor BX4 ,R15

DescriptionA great microcontroller is useless if it cannot physically interact with the real world. When your project demands serious mechanical movement, standard 5V hobby motors simply strip their plastic gears or stall completely. The 12V 300RPM DC Gear Motor is built for heavy lifting, utilizing an all-metal geartrain to guarantee reliable, high-torque performance for your most demanding hardware builds.The Mechanical Advantage of the 37mm GearboxThis component consists of two integrated parts: a high-speed 12V DC motor (spinning natively at 5000 RPM) and a front-mounted 37mm reduction gearbox. By mechanically gearing down the speed, the motor exponentially multiplies its rotational force (torque). The 300 RPM output means the shaft rotates exactly 5 times per second—a highly controllable speed that makes it perfect for driving the wheels of a medium-sized robot chassis or operating a motorized pulley system.Standardized D-ShaftThe output shaft is a robust 6mm diameter cylinder with a flat side, commonly known as a “D-shaft.” This specific shape is critical for high-torque applications, as it allows set-screws and mounting hubs to lock securely onto the flat edge. This guarantees that your wheels, gears, or custom 3D-printed attachments will never slip or spin freely under a heavy load.Powering and Driving the MotorBecause this is a 12V brushed DC motor, it draws significant current and cannot be powered directly by an Arduino or ESP32.To control the direction (forward/reverse) and speed (via PWM), you should pair this motor with a heavy-duty motor driver, such as the L298N Dual H-Bridge or a BTS7960 high-current module.Ensure your power supply or battery pack can comfortably deliver 12V DC to get the maximum rated torque and RPM out of the unit.Key Features:All-Metal Gears: Internally constructed with heavy-duty metal gears to resist wear and prevent tooth-stripping under load.Solder-Ready Terminals: Features large, accessible copper tabs on the rear for easy wire soldering and reliable connections.Face-Mounting Holes: The front plate includes threaded metric holes, making it incredibly simple to mount flush against acrylic, metal, or wood panels.Technical Specifications:Operating Voltage: 12V DCOutput Speed (No Load): 300 RPMBase Motor Speed: 5000 RPMGearbox Diameter: ~37mmShaft Diameter: 6mm (D-Shaft)Motor Type: Brushed DCIdeal Applications:Driving wheels or tracks on heavy DIY robotic platformsBuilding automated curtain openers or motorized window blindsPrototyping custom conveyor belts or dispensing machinesUpgrading worn-out motors in remote-control vehicles or DIY power tools
