3268_1 12V/17.3Kg-cm/18RPM 139:1 DC Gear Motor, 3268_1


The 3268 is a 12 volt gear motor, generating 17.3 Kg-cm of torque at 18 RPM. It's a standard-sized motor suitable for low-torque, high-speed applications.

Since this motor has a lower power output for its size, you can expect it to have a longer lifespan than other motors.

  • 8mm Shaft
  • 111.5mm Motor Length

The planetary gearbox on this motor is more sophisticated than a typical spur gearbox and will provide greater efficiency, higher torque, and quieter motor operation.

The 3268 DC motor connects to either of the following controllers:

  • 1064 - PhidgetMotorControl HC
  • 1065 - PhidgetMotorControl 1-Motor
