Magnet quality and the nonlinearity error
Each AM512B is optimized during the production to give best performance with an ideal magnet when
perfectly aligned.
An ideal magnet would have the polarization border exactly in the middle of the magnet. In reality this is
impossible to achieve repeatably.
Fig. 24: Ideally polarized magnet and not ideally polarized magnet
If the polarization is not exactly in the middle of the magnet then the modulation of the magnetic field has an
offset. The offset represents a mean value of Bn when the magnet is rotated through 360° and Bn is
measured at 2.45 mm distance from the magnet surface and at 2.4 mm radius.
Offset will cause larger than normal integral nonlinearity errors if the AM512B placement is not in the center
of the magnet rotation.
Figure 25 shows the additional integral nonlinearity error caused by misalignment of the AM512B for ideal
and recommended magnets.

Fig. 25: Additional integral nonlinearity error caused by magnet displacement and quality
Total integral nonlinearity is the summation of integral nonlinearity and the additional integral nonlinearity
error caused by magnet displacement.
