Solarbotics GM3 224:1 Gear Motor 90 deg. Output

This 224:1 gearmotor (gearbox with motor) is a great low-cost alternative to modified hobby servos or Tamiya gearboxes. The low-current motor is a perfect match for our micro dual serial motor controller, and the compact size of 2.17" x 1.89" x 0.906" (55mm x 48mm x 23mm) makes this unit an attractive choice for small robot designs.

At 5V, the gearbox and motor provide 50 oz * in. of torque and 38 RPM, which is slightly slower than a servo. The free-running current is 52 mA, and the stall current is 600 mA. A built-in safety clutch engages at approximately 60 oz * in.

This gearmotor comes pre-assemebled, with the gears fully enclosed. There are built-in mounting holes, and the output shaft is 7mm in diameter with two sides flattened.

A custom-molded GMPW plastic wheel for this gearmotor is available.

For a version of this gearmotor with the output shaft parallel to the motor shaft, see the GM2 gearmotor. For a similar but smaller 120:1 gearmotor, see the GM7 gearmotor. For a faster version, see the GM9 gearmotor. To increase the power of this gearbox, you can replace the motor with a higher-power RM2 motor.

Note: This gearmotor does not come with mounting hardware, instructions, or packaging.
