This 200:1 plastic gearmotor (gearbox with motor) is a great low-cost alternative to modified hobby servos. The low-current motor is a perfect match for our qik 2s9v1 dual serial motor controller , and the compact size of 2.54″ x 0.88″ x 0.83″ (64.4 x 22.3 x 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 higher-torque, lower-speed version of the 120:1 plastic gearmotor 90-degree output. At 6 V, the gearbox and motor provide approximately 100 oz-in of torque and 51 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 similar gearmotor with an offset output shaft.
