6V DC MP motor in a metal housing with 30: 1 gearbox

overview

These tiny brushed DC gearmotors are intended for use at 3 volts, but in general, they should be able to comfortably operate in the 3 - 9 V range (rotation can start at voltages as low as 0.5 V). Lower voltages could not be practical, and higher voltages could start negatively affecting the life of the motor. The micro metal gearmotors are available in a range of gear ratios-from 5: 1 up to 1000: 1-and offer a choice between three different motors: high-power (HP), medium-power (MP), and standard. With the exception of the 1000: 1 gear ratio versions, all of the micro metal gearmotors have the same physical dimensions, so they can easily be swapped for another if your design requirements change. Please see the micro metal gearmotor. Comparison of the table for detailed specifications. This dynamically-sortable table can help you find the best blend of torque, torque, and current-draw for your application. A more basic comparison table is available below.

Some versions of the gearmotors are sold with an additional 1mm-diameter output shaft. This 4.5mm-long rear shaft rotor is a motor speed or position feedback.

Note: The 1000: 1 gearmotors can generate enough torque to damage themselves. The stall torque values for those two motors are theoretical, and we strongly recommend you to avoid stalling them.

Gearmotor Dimensions

Micro metal gearmotor dimensions (units in mm).

The gearbox has a long (0.365 "or 9.27 mm), 3 mm-diameter, D-shaped metal output shaft, and brass faceplate has two mounting holes for M1.6 screws (1.6 mm diameter, 0.35 mm thread pitch). gearmotor weighs approximately 0.35 oz (10 g). Versions with the extended motor shaft have a 1mm diameter round shaft that protrudes 4.5 mm from the rear of the motor.

The gearbox on the 1000: 1 and 1000: 1 HP micro metal gearmotors is 12.5 mm long. All of the other micro metal gearmotors have 9mm-long gearboxes, as shown in the above dimension diagram.

Motor Accessories

• Wheels and Hubs: Polaro wheels and the Solarbotics RW2 rubber wheel. You can also use our Pololu universal mounting hubs to mount custom gears.

• Mounting Brackets: Our mounting bracket (also available in white) and mounting bracket are also designed to securely mount the gearmotor while enclosing the exposed gears. We recommend the extended bracket for wheels with recessed hubs, such as the Pololu wheel 42 × 19mm. Our micro metal gearmotors will also work with our 15.5D mm metal gearmotor bracket pair.

• Motor Controllers: We have a number of motor controllers, including our qik 2s9v1 dual serial motor controller and our programmable. Baby Orangutan and Orangutan SVP robot controllers. The inexpensive qik 2s9v1 allows variable speed and direction control; the Orangutans combine a programmable Atmel AVR microcontroller and dual motor driver. All of Pololu AVR library. We also have the DRV8833 dual motor driver carrier, and the TB6612FNG dual motor driver carrier.
