This 143:1 gear motor spins at 70RPM at 5V, drawing 670mA at stall generating 43 in*oz torque (free running at 57.6mA). With a 7mm double-flat output shaft (avoid using the green double flat output - it's not meant to take rotational load), and a built-in clutch and built-in mounting screw holes, you can see why we like these motors!

This 35:1 micro geared motor is a bit larger than our other ones. Nearly twice the weight, this is the one to use if you forsee needing a more durable drive motor. Its fast too! 1050 rpm makes it the fastest micro geared motor we sell. NOTE: The 4.5mm long shaft is too short to use with our Mini Aluminum Hubs. Use the FingerTech Lite Hubs instead.  Specifications at 4.5V: 35:1 - GM19 Typical operating voltage 1.7-5.0VDC No load speed 1050 rpm No load current 130 mA load current 500...

The provided mounting holes in the 143:1 Angled Gear Motors are a convenient way to mount these to your project, but sometimes you just need a different way to mount them. These precision laser-cut steel brackets match the features on the gear motor, and securely clamp them down to your project.Use any #4-sized screw or nut/bolt for assembly, but we use special #4x1/2" screw designed for threading plastic to mount these to our chassis. This screw also does a great job going into the steel...

This original-style GMPW wheel is made to match the Solarbotics GM3 and GM8 gearmotors, and it also matches the Pololu 180:1 90-degree and Offset Shaft plastic gearmotors. This plastic wheel is molded from ABS, and measures just under 2-5/8" across by 0.3" wide. With the included rubber band tire, the total wheel diameter is 2-5/8".Included PartsOne wheelTwo rubber band tires (one is a spare)One screw for mounting0-PL199
