The 46.85:1 metal spur gearbox delivers 220 RPM no-load speed with up to 15 kg·cm of stall torque, making it well suited for robotics drive systems and mechanisms requiring moderate speed with strong torque.\n\nThe cylindrical form factor (just under 25 mm diameter) and 4 mm D-shaped output shaft allow easy mounting with standard Pololu 25D brackets and hubs. The output shaft extends 12.5 mm from the gearbox face plate.\n\nKey Features\n\n\n46.85:1 Gear Ratio – Metal spur gearbox for durability under load\n\nHigh-Power Motor – 12V brushed DC motor with strong torque output\n\n220 RPM No-Load – Good balance of speed and torque\n\n15 kg·cm Stall Torque – Sufficient for driving robot wheels and mechanisms\n\n4 mm D-Shaft Output – 12.5 mm extension, compatible with standard hubs and couplers\n\nCompact 25D Form Factor – Under 25 mm diameter cylindrical body\n\n\nSpecifications\n\n\nOperating Voltage: 12V\n\nGear Ratio: 46.85:1\n\nNo-Load Speed: 220 RPM\n\nNo-Load Current: 250 mA\n\nStall Torque: 15 kg·cm (210 oz·in)\n\nStall Current: 5.0A\n\nOutput Shaft: 4 mm D-shaped, 12.5 mm long\n\nMotor Diameter: ~25 mm\n\nMotor Type: HP (High Power)\n\n\nIdeal For\n\nRobot drive systems and wheeled platforms\nMotorised mechanisms and actuators\nConveyor and positioning systems\nProjects requiring moderate speed with high torque\n\n\nPackage Contents\n\n1× 47:1 Metal Gearmotor 25Dx52L mm HP 12V\n\n\n\nTip: Need closed-loop speed or position control?
