Solarbotics GM3 224:1 Gear Motor 90 deg. Output

This 224:1 gearmotor (gearbox with brushed DC motor) 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 7mm in diameter with two sides flattened (the “D” output is not meant to be used). A built-in safety clutch engages at approximately 60 oz-in.

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).
