What can I use my gearbox and motor for?

This small metal motor with its built-in gearbox is ideal for projects and application were space is at a premium. 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. Designed to fit into a range of hobby, modelling, R&D, educational and even small scale industrial projects and products. This solidly constructed steel and brass motor is mounted on a 1mm thick steel bracket to prevent movement while it’s working. The motor and gearbox incorporates a high quality three pole motor with sintered bronze bearings and has a 4 mm diameter central output shaft.

(Motor speeds may vary by ±12.5%)

This motor is also available without the gearbox.

What is the lowest RPM this motor and gears can do?

Asked by: DanH
This will run at 159 rpm @1.5 V 1.5V is the lowest rated voltage, so 159 would be the lowest rpm.
