Here's what I think you said, but I can't tell for sure:

1) Your 775 motor is connected to a gear box.

2) The output shaft of that gearbox is 1/2" diameter

3) There's a sprocket on the output shaft of the gearbox

4) There's a chain on that sprocket

5) That chain goes to a sprocket connected to the wheel

6) The wheel rides on a dead axle.


How and where do you plan to physically mount the encoder?

What is the gear ratio of the gearbox?

What is the tooth count on the two sprockets?
