What output does this motor gearbox provide?

With a torque of up to 219 gf.cm (0.021 Nm) and rotations per minutes of up to 604 rpm, this is a versatile motor gearbox for many applications. The motor works on 1.5-3 volts and can change the run direction based on the input polarity. The light weight 15:1 ratio motor gearbox is just 75g and with its compact 27mm x 27mm x 50mm (67mm including shaft) size and built on mount, this is a great addition to any experiment or project.

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.

Can this motor be adjusted to work at different rpms? If so how? I was hoping to mount two motors to run simultaneously. Think a spinning table, with another table running perpendicular for 2 plane spinning of an object, can this be done? thanks
