Yes, it is indeed similar to the Inductosyn, which also has a “holistic” rotor, flat construction, and very high accuracy. However, it has a number of additional advantages: It consumes much lower power (in fact lower than any other position encoder) It needs no slip‐rings, or rotary transformers It is much lower in weight It includes all of its support electronics on‐board It is insensitive to magnetic fields and has no magnetic signature
