Multipolar Magnetization Fixture:
achieve single and total pitch errors lower than 0.03°

The NT Multipolar is a patent-pending fixture for axial multipolar magnetization, which keeps pitch errors negligible — even with double traces on the same sensor disk. Laboratorio Elettrofisico has designed this fixture to achieve single and total pitch errors lower than 0.03° using very high precision CNC-machined windings and an innovative engineering process. The NT Multipolar fixture is embedded in epoxy resin and encased in an IP30 box.

Key benefits
  • Single and total pitch errors lower than 0.03°
  • Precision machining of solid copper windings allows adjustable relative orientation for different traces on the same disc
  • Linear geometries are also available with either straight or any type of skewed interpolar dead zone
Applications
  • High pole patterns axially or radially, even obliquely oriented
  • Single trace sensor disks
  • Double trace sensor disks
  • Regularly spaced sensor disks
  • Irregularly spaced sensor disks
