Figure 11. Magnetic Field Lines with Spacer Between Magnet and Iron Shaft
If the magnet has to be mounted inside a magnetic shaft, a possible solution is to place a non-magnetic spacer between shaft and magnet, as
shown in
IC. The distortion remains reasonably low.
7.1.6 Summary
www.austriamicrosystems.com/AS5215
Small diameter magnets (<6mm Ø) have a shorter linear range and allow less lateral misalignment. The steeper slope allows larger axial
distances.
Large diameter magnets (>6 mm Ø) have a wider linear range and allow a wider lateral misalignment. The flatter slope requires shorter axial
distances.
The linear range decreases with airgap; Best performance is achieved at shorter airgaps.
The ideal vertical distance range can be determined by using magnetic range indicators provided by the encoder ICs. These indicators are
named MagInc, MagDec, MagRngn, or similar, depending on product.
