What size is this motor gearbox?

At 39 mm x 47 mm x 71 mm (96 mm including shaft) this large motor with an integrated gearbox is great for most mid-sized projects. Capable of producing up to 1800 rotations per minute (rpm) and torque up to 1000gf.cm (0.098Nm) at 12V this is a great all-round motor with a good rpm and torque suitable for a wide range of projects. The direction of rotation can be reversed by changing the input polarity. The motor comes with its own 1mm thick plated steel bracket mount.

What can I use this motor gearbox for?

This is a powerful motor with an integral gearbox suitable for heavy-duty industrial or model applications. The motor is capable of high torque transfer through the gears. The built-in gearbox can increase your turning power (torque) at a reduced rotations per minute from the motor. The optimum ratio for this will depend on your project. Solidly constructed from steel and brass with sintered bronze bearings, a high quality three pole motor and a 5.98mm diameter central output shaft. This motor gearbox is ideal for DC 4.5-15V powered mechanisms with a wide range of application from industrial uses to modelling or hobbies or to demonstrate mechanical principles for educational kits.
