More info


Pololu HPCB engine equipped with a 15,25:1 metal gear ratio. The motor is designed for 6 V power supply and generates a torque of 0.25 kg * cm. The current consumed by the loaded motor is about 100 mA, while the maximum current consumed under load is 1500 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. In this set, the manufacturer uses the HPCB series engine, which means that it is equipped with carbon brushes. This is a much more durable solution than the previously used brushes made of blades. 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.
