Overview

These tiny, high-quality motors are intended for use at 6 V. In general, these kinds of motors can run at voltages above and below this nominal voltage, so they should comfortably operate in the 3 – 9 V range. Lower voltages might not be practical, and higher voltages could start negatively affecting the life of the motor. All of the micro metal gearmotors have the same physical dimensions, but they come in a wide range of gear ratios—from 5:1 up to 298:1—and let you choose between two different motors: high-power (HP) and standard. This means you can choose the version that has the ideal blend of speed, torque, and current-draw for your particular application.

Gearmotor Dimensions

Micro metal gearmotor dimensions (units in mm).

This motor has a long (0.365" or 9.27 mm), D-shaped metal output shaft, and the brass faceplate has two mounting holes threaded for M1.6 screws (1.6 mm diameter, 0.35 mm thread pitch). It weighs approximately 0.35 oz (10 g).

Motor Accessories

 

Pololu wheel 42x19mm with micro metal gearmotor.
A pair of Pololu universal aluminum mounting hubs for 3 mm shaft.
  • Mounting Brackets: Our  extended mounting bracket are specifically designed to securely mount the gearmotor while enclosing the exposed gears. We recommend the extended mounting bracket for wheels with recessed hubs, such as the Pololu wheel 42x19mm.
Pololu micro metal gearmotor bracket extended with micro metal gearmotor.
  • Quadrature Encoder: We offer a quadrature encoder for this motor that works with our extended bracket and 42x19mm wheel and provides feedback about wheel rotation (direction and speed). The encoder can be purchased as an individual unit or as part of an encoder set that includes two encoders, a pair of extended brackets, and a pair of 42x19mm wheels—just pick the particular micro metal gearmotor that best suits your application and you have a solution for closed-loop motor control.

 

  • Motor Controllers: We have a number of motor controllers that make it easy to drive these micro metal gearmotors, including our programmable mini driver robot controllers and Micro magician controller w/ built in Accelerometer. The inexpensive controller allows variable speed and direction control of two small, brushed DC motors using a simple serial interface;  combine a programmable Atmel AVR microcontroller and dual motor driver all in a single package and make interfacing with the motor drivers simple when you use our Pololu AVR library. You can also use the simple motor driver carrier board.
