Solarbotics GM8 143:1 Gear Motor Offset Output
We can get 1 units in Australia from Pololu. If you order today, we can dispatch this stock between Mar 02, 2021 - Mar 09, 2021.
This 143:1 gearmotor (gearbox with brushed DC motor) is a faster version of the GM2 gearmotor. It is a great low-cost alternative to modified hobby servos or Tamiya gearboxes. The low-current motor is a perfect match for our qik 2s9v1 dual serial motor controller, and the compact size makes this unit an attractive choice for small robot designs.
This gearmotor comes pre-assembled, with the gears fully enclosed. There are built-in mounting holes, and the output shaft is 7 mm in diameter with two sides flattened. Please note that the output shaft is slightly shorter than on the GM2 and GM3 gearmotors. Also, the green end of the output shaft should not be used (it is difficult to get to, anyway). This motor also comes with a built-in safety clutch.
Compatible products include a custom-molded GMPW plastic wheel, and the Solarbotics GMW motor mount, which can be used as a wheel itself or as a mounting point for other wheels or mechanisms. Solarbotics makes a mounting bracket that works with this motor, and our L-brackets and extended L-brackets for plastic gearmotors are also compatible with this motor (though you might need longer screws than the ones included with the Pololu brackets).
