Abstract (en)
[origin: EP0877396A1] A metal/ferrite laminate magnet (100) has perforations forming apertures (125) in the magnet (100). The magnet is formed of outside metal plates (105) surrounding a sandwich of two layers of ferrite material (115). The outside metal plates (105) allow the perforations (125) to be made in the magnet (100) before sintering of the magnet (100) and maintain the alignment of the holes (125) during sintering. The metal plates (105) also provide the magnet (100) with mechanical robustness and rigidity and prevent cracking occurring between adjacent apertures (125). <IMAGE>
