Hello Renan,
Are you set on using an inductive solution for this? We have some Hall collateral that showcases this application. See [FAQ]: What Hall-effect sensors are used for Brushless DC Motor commutation for more information.
If you are set on inductive, we don't have any examples of the UVW signals, but you may be able to setup something similar using an inductive coil. If this is the route you want to go, what would the speed of the rotation be?
Best Regards,

Hello Justin,
Good day.
My customer is looking for a UVW solution for a Hub Motor. Since the shaft is stationary, they are looking for a suitable encoder to remove the hall sensors from the winding. Also, since the Motor controller can accept UVW only (at 5V) they thought of Inductive sensing.
However, if you have some other options, please do suggest.
Regards,
Renan
Hello Renan,
We don't have any full solutions like that in inductive, but you could use 3 of the LDC0851 devices to act as switches for the UVW signals. If you setup the target and sensor coil properly, you could replicate the UVW signals using the digital outputs. This seems like the best fit for this application but there is also our LDC3114 that can do raw data and digital outputs. It has a button algorithm for the digital outputs but depending on the speed of the motor and target design, you may be able to adjust the settings for it to work in this application.
One other thing to consider is that either of these solutions would need a level shifter for the output to reach 5V.
