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

Product Description

The 3268 is a 12 volt gear motor, generating 17.3 Kg-cm of torque at 18 RPM. Since this motor has a lower power output for its size, you can expect it to have a longer lifespan than other motors.

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.

Motor Controller and Connection

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

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

Warnings

warning The torque this motor produces when it stalls exceeds the rated strength of the gearbox. This means that stalling or very heavily loading this motor can cause serious damage to the gearbox. To avoid damage, avoid sudden loads or any load higher than the Maximum Strength of Gears spec.
