Solarbotics GM14a 298:1 Mini Metal Gear Motor
The Solarbotics GM14a 298:1 mini metal gear motor is a compact (1.14" x 0.39" x 0.47") brushed DC motor with metal gears, very similar to the Sanyo NA4S motor. The major difference is that these Sanyo motor look-a-likes have brass front faceplates (not steel ones), and cost less.
These miniature brushed DC 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.

Note: These gearmotors do not come with mounting hardware, instructions, or packaging. The brass faceplate has two mounting holes threaded for 1.7 (dia) x 0.35 (mm/thd) x 4mm long screws (M1.7 × 4 mm), and our micro metal gearmotor bracket (sold separately) gives you even more mounting options.
