Solarbotics GM9 143:1 Gear Motor 90 deg. Output
This 143:1 brushed DC gearmotor is the right-angle version of the GM8 and the high-speed version of the GM3.
This 143:1 gearmotor (gearbox with brushed DC motor) is a faster version of the GM3 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. 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. A mounting bracket is not required but can be purchased separately for more versatile installation.

To increase the power of this gearbox, you can replace the motor with a higher-power RM2 motor. For a replacement motor, see the RM3 motor.
