This 120:1 gearbox with 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.
This 120:1 plastic 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 qik 2s9v1 dual serial motor controller or micro dual serial motor controller, and the compact size of 2.54" × 0.88" × 0.83" (64.4 × 22.3 × 21 mm) 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 200:1 plastic gearmotor 90-degree 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 sheer.
This gearmotor comes pre-assembled, with the gears fully enclosed. There are built-in mounting holes, and the output shaft is 6 mm long and 7 mm in diameter with two sides flattened. The output shaft is at a 90° angle from the axis of the motor shaft; we also sell a version of this gearmotor with an offset output shaft.
A custom-molded GMPW plastic wheel for this gearmotor is available in a variety of colors.
