Does anybody have a picture/ diagram of the integrated encoder of the falcon?
We have a broken NEO motor in our workshop, and last week out of curiosity I looked on how its hall effect sensors are used as an encoder to determine the motor position.
I wanted to find out how a Falcon motor determines its position, because the method the NEO uses doesn’t seem like it could reach the 2048 cpr the falcon has, but I couldn’t find any information about it online.
If anyone could explain how it works it would be very helpful, and if possible please include a picture, because I am sure a picture that explains that would be really cool.
IIRC they use roughly the same method to determine their position. While the NEO is only 50 cpr, the falcon uses the same idea of a bunch of tiny hall efect sensors in a ring on the chip to read the flux density distrabution of a diametrically polarized magnet across the ICs surface. Only difference is the falcon has a higher resolution chip, similar to what youd find in a SRX mag encoder or cancoder. Its literely just a single chip so this is the closest I coud find to a diagram.
The magnetic is on top of the shaft. The transducer is on the controller bolted to the motor. The software required to align it is not publicly available. This one is officially broken.
