Mini Metal Gearmotor 26:1 (438 RPM)

This motor has a 3mm D-shaped metal output shaft that matches the Pololu wheel 42x19mm and 32x7mm. The face plate has two mounting holes threaded for M2 screws.

These motors are intended for use at 6V. 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.

Replaces:ROB-8913

  • 25:1 gear ratio
  • 438rpm @ 6V
  • 44mA @ 6V
  • 6 oz inches torque @ 6V

    Will this motor interfere with this? https://www.sparkfun.com/products/10530

    from my experience, these are EMI bombs. Make sure you don't have any non-differential encoders or other sensitive parts in the system.

      Have you tried placing a small ceramic capacitor across the motor terminals?

  • dragonet80 / about 9 years ago / 1

    In description you say it has a 7mm D-shaped shaft, but it is 3mm. And wich reduction ratio is correct 26:1 (title) or 25:1 (features)?

  • doobie / about 9 years ago / 1

    Will sparkfun carry motors that are good for DIY multi-copters?
