2-Pole Rotary Encoder Magnets
In the end application, the magnet is attached to a rotating part and the Bx, By sensor measures the angular position = atan2 (Bx,By) of the magnet. For this application the in-plane field is important.
Some of the magnet quality issues include:
- Inhomogeneity of field direction --> Angle error
- Bxy out of range
With the Magcam MiniCube3D the spatial distributions of the Bxy field component and azimuth field angle are readily measured and analyzed, providing many quality aspects of the magnet:
- Azimuthal angle error distribution
- Bxy field distribution
- Total harmonic distortion
- Circle/ring/volume analysis without rotating
- Magnetic vs mechanical center
- Volume analysis with single plane measurement
Advanced algorithms allow for noise free analysis at any distance from the magnet.
