Pololu High-Power 10:1 6V Micro Metal Gearmotor with Extended Motor Shaft

This is a Pololu miniature high-power (HP), 6V brushed DC motor with a 9.96:1 (10:1) metal gearbox with an extended motor shaft for use with encoders. This 1 mm diameter shaft extends 4.5 mm from the rear of the motor and rotates at the same speed as the input to the gearbox. These versions work with our separately available Pololu encoders.

The motor has a cross-section of 10×12 mm, and the D-shaped gearbox output shaft is 9mm long and 3mm in diameter.

We stock a range of these Pololu tiny brushed DC gearmotors, available in a range of gear ratios in either high-power (HP), medium-power (MP) or low-power (LP) with precious metal brushes. In general, these kinds of motors can run at voltages above and below their nominal voltages; lower voltages might not be practical, and higher voltages could start negatively affecting the life of the motor.

With the exception of the 1000:1 gear ratio versions (not currently stocked), all of the micro metal gearmotors have the same physical dimensions, so one version can be easily swapped for another if your design requirements change.

Please see the datasheet for more information, including detailed performance graphs for each micro metal gearmotor version available from Pololu.

Note: Stalling or overloading gearmotors can greatly decrease their lifetimes and even result in immediate damage. The recommended upper limit for instantaneous torque is 2.5 kg⋅cm (35 oz⋅in) for the 380:1 and 1000:1 gearboxes, and 2 kg⋅cm (25 oz⋅in) for all the other gear ratios; we strongly advise keeping applied loads well under this limit. Stalls can also result in rapid (potentially on the order of seconds) thermal damage to the motor windings and brushes, especially for the versions that use high-power (HP and HPCB) motors; a general recommendation for brushed DC motor operation is 25% or less of the stall current.

Motor Accessories

• Encoders - we stock a number of Pololu magnetic encoders for these extended shaft motors
• Wheels and hubs - The micro metal gearmotor’s output shaft match our assortment of Pololu wheels. You can also use our Pololu universal mounting hubs to mount custom wheels and mechanisms to the micro metal gearmotor’s output shaft, and you can use our 12mm hex wheel adapter to use this motor with many common hobby RC wheels.
• Mounting brackets - Our mounting bracket (also available in white) and extended mounting bracket are specifically designed to securely mount the gearmotor while enclosing the exposed gears. We recommend the extended mounting bracket for wheels with recessed hubs, such as the Pololu wheel 42×19mm.
• Quadrature encoders - Pololu offer several quadrature encoders that work with our micro metal gearmotors.
• Motor controllers and drivers: We have a number of Pololu motor controllers, motor drivers, and robot controllers in there store
