The 3271E is a 24 volt gear motor, generating 20.4 Kg-cm of torque at 139 RPM. It's a large motor that provides lots of torque, even at higher speeds.
This motor comes equipped with an E4P US Digital Encoder, which keeps track of the motor's rotation, allowing you to control your motor precisely.
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 3271E DC motor connects to the 1065 - PhidgetMotorControl 1-Motor.
