Abstract:
An apparatus includes a shaft and a first code ring including a first number of pole pairs. The first code ring is attached to the shaft. The apparatus includes a second code ring including a second number of pole pairs different from the first number. The second code ring is attached to the shaft and spaced apart from the first code ring. The apparatus includes a first magnetic field sensor between the first code ring and the second code ring for sensing a first superposition of magnetic fields provided by the first code ring and the second code ring.
