228:1 Plastic Gearmotor Offset Output Pololu plastic gearmotor offset output with opened gearbox. This 228:1 plastic gearmotor (gearbox with brushed DC motor) is a great low-cost alternative to modified hoy 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 higher-torque, lower-speed version of the 120:1 plastic gearmotor offset output. At 6 V, the gearbox and motor provide approximately 100 oz-in of torque and 45 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 similar gearmotor with a 90 output shaft. There are two built-in mounting holes that work with our stamped aluminum L-bracket and extended stamped aluminum L-bracket, as shown in the pictures below: Plastic gearmotor with offset output (item Plastic gearmotor with offset output (item 1118 or 1119) mounted with Pololu 1118 or 1119) mounted with Pololu stamped aluminum L-bracket. extended stamped aluminum L-bracket. This gearmotor is compatible with the Solarbotics GMPW plastic wheel, which is available in a variety of colors.Dimensions (in mm) of the 120:1 and 228:1 plastic gearmotors with offset outputs.
