This 224:1 gearmotor (gearbox with brushed DC motor) has a low-current motor and provides power and speed that is comparable to an RC servo at a fraction of the cost.

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. 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.
