<p>Tubular inductive component is manufactured with an airgap to produce a high magnetic reluctance. The material is a hard, brittle ceramic which has magnetic properties, and a conductor is fed through the hollow of the tube. A laser beam is concentrated on the outer surface of the tube to cause part of the material to evaporate. The tube is then moved in the axial direction relative to the beam which produces a longitudinal slot in the outer surface of the material. The guide slab has a V shaped channel for sealing the workpiece. The size and shape of the elongated holes can be controlled. The focussing of the beam is such that the material structure of the remote wall will remain unaffected.</p> |
