Replaced by the 3268_1 and the 3531 - Optical Rotary Encoder HKT22, sold separately.
The 3268E 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.
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 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. |
