<p>A stator for electromagnetic stirring surrounds a continuous casting mold. A conducting winding arrangement is provided for creating an electro-magnetic field in the mold and rotating about the axis thereof. The conducting winding arrangement uses multiple phase electrical energization and has, for each phase, a group of conductors arranged to carry current down one side of the mold and up the opposite side. The groups of conductors corresponding to the electrical phases arranged so that the overall result of such groups is to cause a magnetic field, with flux lines transverse to the mold axis to rotate about the mold axis at a rotational frequency dependent upon the characteristics of the electrical supply and the number of winding groups. A magnetically permeable path is provided surrounding such winding groups which path is substantially all located outside said windings. The design avoids the salient pole pieces required in prior art arrangements.</p> |
