This Pololu 50:1 Micro Metal Gearmotor has a long 0.365" (9.27 mm), D-shaped metal output shaft that matches the Solarbotics RW2 - Large Rubber Wheel and the Pololu Wheel 42x19 mm (Pair) . The brass faceplate has two mounting holes threaded for M1.6 screws (1.6 mm diameter, 0.35 mm thread pitch), or you can use Pololu's Pololu Micro Metal Gearmotor Bracket (pair) or Pololu Micro Metal Gearmotor Mounting Bracket (Extended-Pair) , which are specifically designed to securely mount the gearmotor while enclosing the exposed gears.

These 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.

Customer Reviews

Based on 4 reviews
Surprisingly powerful.

They were smaller than I expected, which saved me some weight. Surprisingly powerful for their small size, plenty of speed and torque. I'm using them for outboard motors on an amphibious robot with 1.5" props.

Great motor

Small quality motor that performs to specifications.

Good quality, fast shipping

Really good quality with well detailed manual. Fast shipping to Hungary: 1 week.

Does what it should

Nice little motor and I even got to see the inside when I accidentally pulled it apart - not the fault of the motor just my error.
