A high-power 12V brushed DC gearmotor from Pololu's 25D mm metal gearmotor range. 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.

The 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.
