120:1 Plastic Gearmotor, 90º Output

This 120:1 plastic gearmotor, which combines a gearbox with a brushed DC motor, is an excellent low-cost option compared to modified hobby servos or Tamiya gearboxes. Its low-current motor is an ideal match for our qik 2s9v1 dual serial motor controller, Baby Orangutan robot controller, or DRV8833 dual motor driver carrier. With its compact size, it's a top choice for small robot designs. The recommended operating voltage for this motor ranges from 3 to 12 V. It's a lower-torque, higher-speed version of the 200:1 plastic gearmotor with a 90-degree output. At 6 V, the gearbox and motor offer about 75 oz-in of torque and 85 RPM. The free-running current is 70 mA, and the stall current is 800 mA. The gearbox has a built-in safety clutch that usually slips before the gear teeth break. The gearmotor comes pre-assembled with fully enclosed gears. The output shaft is 6 mm long and 7 mm in diameter with two flattened sides, and it's at a 90° angle from the motor shaft. We also have a version with an offset output shaft.

Using this gearmotor is quite simple. First, make sure the operating voltage you use is within the recommended range of 3 - 12 V. Connect the motor to the appropriate controller like the qik 2s9v1, Baby Orangutan, or DRV8833. When using it in your small robot design, its compact size will make installation easy. Just remember that it's a lower-torque, higher-speed option compared to some others. Don't overload the motor beyond its capacity. The built - in safety clutch is there to protect the gears, but it's still best to operate within the specified torque and current limits. For maintenance, keep the gearbox clean and check the connections regularly. If you notice any unusual noises or performance issues, stop using it and check for loose parts or damage. Also, if you need a different output shaft configuration, we have a version with an offset output shaft available.
