How to calculate the accuracy of the resolver?
In terms of linearity or in terms of resolution?
Resolution is hard to quantify, as they are analogue devices, so the
accuracy is dependent on the measurement device, not the sensor.
Assuming this is being used with the Pico Systems resolver
converter, which uses the Analog Devices AD2S1200 converter
chip, resolution is fixed at 4096 quadrature counts/rev.
AD claims 11 arc minutes accuracy for the chip itself. I
don't know if you add that error directly to the resolver
accuracy or add it in quadrature.
