The Solarbotics GM18 30:1 mini metal gear motor is a compact (1.14" x 0.39" x 0.47") high-quality motor with metal gears similar to the Sanyo motors such as NA2S NA3S and NA4S. The major difference is that these Sanyo motor look-a-likes have brass front faceplates (not steel ones) and cost less.
These high-quality miniature metal gear motors have 3 mm diameter output shafts that mate fairly well with any 1/8-inch hole output device including the Solarbotics RW2 high-traction rubber wheels. Alternatively you can use the Pololu universal mounting hub to mount custom wheels and mechanism to the micro metal gearmotor˙s output shaft.
The brass faceplates have two mounting holes threaded for 1.7 (dia) x 0.35 (mm/thd) x 4mm long screws (M1.7 × 4 mm) or you can use our mounting bracket which is specifically designed to securely mount the gearmotor while enclosing the exposed gears.
These small motors come in a variety of gear ratios have a compact size (1.14" x 0.39" x 0.47") and weigh only 0.29 oz making them a great choice for small robot designs ? and controlling these low-current motors is a snap with our qik 2s9v1 dual serial motor controller.
