With a cross section measuring only 10 × 12 mm (0.39″ × 0.47″), these small brushed DC gearmotors are available in a wide range of gear ratios—from 5:1 up to 1000:1—and with five different motors: high-power 6 V and 12 V motors with long-life carbon brushes (HPCB), and high-power (HP), medium power (MP), and low power (LP) 6 V motors with shorter-life precious metal brushes. With the exception of the 1000:1 gear ratio versions, all of the micro metal gearmotors have the same physical dimensions (though the terminal size and separation on the HPCB versions differ slightly from the other versions), so it is generally easy to swap one version for another if your design requirements change.
