This 12V DC geared motor with encoder features a 131:1 metal gearbox and built-in quadrature encoder, delivering low-speed, high-torque output with integrated rotational feedback. The encoder output enables position and speed detection, making this drive suitable for robotics, autonomous vehicles, motion control systems and feedback-based mechanisms requiring reliable feedback and torque at low speeds.
Product Description
General Description
This 12V DC geared motor with encoder combines a DC motor, a metal gearbox with a 131:1 reduction ratio, and an integrated encoder circuit into a compact actuator assembly. The gear reduction increases torque and provides a lower output speed, while the encoder offers rotational feedback useful for closed-loop control and monitoring.
The encoder generates quadrature signals corresponding to motor shaft rotation, supporting applications that require position or speed sensing integrated with the power train.
