This rugged wheel is designed to fit securely on the output shafts of our micro and 15.5D metal gearmotors. These gearmotors should be mounted onto the side of the hub with the protruding teeth, as shown on the right. The output shaft will slide into the socket easily at first but will achieve a snug fit when pressed through to the other edge of the hub.
The output shafts on the Solarbotics metal gear motors will also fit these wheels, but because they are shorter they will have to be mounted onto the other side of the wheel where the fit is tighter (which means the Solarbotics metal gearmotors will not work with the quadrature encoder associated with this wheel). These wheels will also work in this orientation on theorientation on the Pololu plastic gearmotors with 3mm D-shaft outputs.
- Diameter: 1.65" (42 mm)
- Width of tire: 0.75" (19 mm)
- Weight: 0.66 oz (19 g)
The following oscilloscope capture shows the two encoder output channels while the 42×19mm wheel is spinning at close to 630 RPM. The two channels are approximately 90° out of phase, allowing you to determine both rotational speed and direction.
- Size: 42 x 19 mm
- Weight: 19 g1
- Shaft diameter: 3 mm2
- 1. Per wheel, including tire.
- 2. D-shaped hole for press fit onto Pololu micro and mini metal gearmotors.
