RB-Pol-266
200:1 Plastic Gearmotor 90 Degree Shaft
This 200:1 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 51 RPM and a
stall torque of approximately 100 oz-in.
This 200:1 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 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 - 12V.
This is a higher-torque, lower-speed version of the 120:1 plastic gearmotor 90-degree output. At 6V, the
gearbox and motor provide approximately 100 oz-in of torque and 51 RPM. The free-running current is
70mA, 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 at a 90° angle from the axis of the
motor shaft; we also sell a similar gearmotor with an offset output shaft. There are two built-in
mounting holes that work with stamped aluminum L-bracket and extended stamped aluminum L-
bracket.
