120:1 Plastic Gearmotor, Offset Output
Pololu item #: 1119
This 120:1 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. At 6 V, it has a free-run speed of 85 RPM and a stall torque of approximately 75 oz-in. Though the product picture shows two gearmotors, this product is for a single motor.

Overview
This 120:1 plastic 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, Baby Orangutan robot controller, or DRV8833 dual motor driver carrier, and the compact size makes this unit an attractive choice for small robot designs. The recommended operating voltage range for this motor is 3 – 12 V.
This is a lower-torque, higher-speed version of the 228:1 plastic gearmotor offset output. At 6 V, the gearbox and motor provide approximately 75 oz-in of torque and 85 RPM. The free-running current is 70 mA, and the stall current is 800 mA. The gearbox is protected by a built-in safety clutch that will typically slip before gear teeth can shear.
This gearmotor comes pre-assembled, with the gears fully enclosed, and the output shaft is 6 mm long and 7 mm in diameter with two sides flattened. The output shaft is along the same axis as the motor shaft, but offset; we also sell a version of this gearmotor with a 90° output shaft.
