Get better magnetization on magnet edges with the SAT Multipolar magnetizing fixture
Designed by Laboratorio Elettrofisico’s R&D Team, the SAT Multipolar magnetizing fixture has one single magnetization solid bar for each slot in place of a multiwire slot. The result: better magnetization of the magnet edges.
The SAT Multipolar is composed of two linked circuits, a primary and a secondary. The primary circuit is composed of a few turns of enameled wires; the secondary circuit is a single solid copper conductor. On the primary, low current is connected to the high voltage side of the capacitor discharging unit. On the secondary, the same power is adapted to a low voltage and an extremely high current. As a result, this fixture requires a reduced amount of insulating material and concentrates higher current density very close to the magnet edges. Both circuits add a magnetization field during the pulse. The fixture is encased in an IP30 box.
- Complicated step skewed geometries
