I'm exploring how to set up wired control for more than 8 focus motors, specifically looking into the Tilta Nano II focus motor. I came across a teardown that revealed it uses a BLDC motor and a magnetic encoder connected by just three wires. This seems insufficient for direct motor control and encoder feedback without multiplexing. I'm wondering what the best approach would be to modify these for full wired control. Should I replace the existing motor and connect the motor and encoder separately? Also, does the motor look like it's a standard size? Any insights would be greatly appreciated, as I've had no luck finding guidance online!

You might want to double-check your setup. As far as I know, the Tilta Nano II doesn't use an encoder on the motor itself—it's likely a standard sensorless BLDC. The person sharing the teardown might have misled you. There could be a sensor at the output of the gear train instead if you're seeing any encoder-like behavior. Overall, going with a standard setup could save you some headaches!
