More info


Pololu DC motor equipped with a 15,25:1 metal gear ratio. The motor is designed for 12 V power supply and generates a torque of 0.25 kg*cm. The current consumed by the loaded motor is about 70 mA, while the maximum current consumed under load is 1600 mA. The motor has an extended shaft on the opposite side of the motor, which makes it easy to install an encoder or other shaft position sensor. The transmission has a D-shaped output shaft with a diameter of 3 mm, which simplifies the installation of the further part of the drive system.
