Note: Stalling or overloading gearmotors can greatly decrease their lifetimes and even result in immediate damage. Stalls can also result in rapid (potentially on the order of seconds) thermal damage to the motor windings and brushes; a general recommendation for brushed DC motor operation is 25% or less of the stall current.
These motors are intended for use at 12 V, though in general, these kinds of motors can run at voltages above and below the nominal voltage (they can begin rotating at voltages as low as 1 V). Lower voltages might not be practical, and higher voltages could start negatively affecting the life of the motor.

Gearmotor accessories
The face plate has six mounting holes evenly spaced around the outer edge threaded for M3 screws. These mounting holes form a regular hexagon and the centers of neighboring holes are 15.5 mm apart. We carry two brackets for these gearmotors: a stamped aluminum L-bracket (sold in pairs) and a sturdier, tombstone-style machined aluminum bracket (sold individually):

The 6 mm diameter gearbox output shaft works with the Pololu universal aluminum mounting hub for 6mm shafts, which can be used to mount our larger Pololu wheels (80mm- and 90mm-diameter) or custom wheels and mechanisms to the gearmotor’s output shaft as shown in the left picture below. Alternatively, you could use our 6mm scooter wheel adapter to mount many common scooter, skateboard, and inline skate wheels to the gearmotor’s output shaft as shown in the right picture below:

For a general-purpose hex adapter, consider our 12mm hex wheel adapter (also available in an extended version), which lets you use these motors with many common hobby RC wheels, including Dagu Wild Thumper Wheels:

We have a number of motor controllers and motor drivers that work with these 37D mm metal gearmotors. In particular, we recommend our VNH5019-based motor drivers, for which we have basic single and dual carriers. If you are looking for higher-level control interfaces, such as USB, RC, analog voltages, or TTL serial, consider our Simple Motor Controller 18v7 or (Simple Motor Controller 18v15, if you want something that will run a little cooler), Jrk 12v12, or TReX motor controller.

We have an assortment of Hall effect-based current sensors to choose from for those who need to monitor motor current:
