Details

Compact 12V motor built for smooth, stable low-speed motion in gimbals, pods, and LiDAR mechanisms.

Encoder integration support includes AS5048A and AS5600 options, with compatibility noted for 12-bit and 14-bit encoders.

Slip-ring compatibility helps simplify continuous-rotation builds while keeping control stable at low speeds.
