Test apparatus for linear scanning of the pole faces

Test device (1) for linear scanning of the pole faces of a VCM system (10) which are arranged two mutually parallel surface having separated by an air gap pole faces, with a magnetic field probe, which is inserted parallel to the pole faces in the air gap and being pivotable in a plane parallel to the pole faces plane for magnetic field measurements at various locations in the air gap, and an evaluation device for determining the magnetic flux densities of individual Polflachenabschnitte from the coil (2) induced voltages characterized, that a coil (2) is provided as a magnetic field probe, and it is rotated about its coil axis
