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.

Magcam MiniCube3D

The Minicube3D is a 3D magnetic field camera, providing quantitative (Bx,By,Bz) magnetic field mapping in a 12.7mm x 12.7mm 2D plane with a 0.1mm spatial resolution, measured at high speed.

Magcam MiniTable Working Platform

The MiniTable is a working platform for measuring small magnets, to be combined with the MiniCube1D or MiniCube3D magnetic field camera.

Magcam Portal/Combi Scanner

The Magcam Portal Scanner is a high-speed 3-axis motorized mapper with an integrated MiniCube1D or MiniCube3D magnetic field camera for measuring large magnets and magnet assemblies.
