POLOLU-4742 · Pololu
This gearmotor is a powerful brushed DC motor with 30:1 metal gearbox intended for operation at 12 V. The gearbox is composed mainly of spur gears, but it features helical gears for the first stage for reduced noise and improved efficiency. These units have a 16 mm-long, 6 mm-diameter D-shaped output shaft. This gearmotor is also available with an integrated encoder. Key specifications: voltage no-load performance stall extrapolation 12 V 330 RPM, 200 mA 14 kg⋅cm (190 oz⋅in), 5.5 A (Pololu item #4742)
