PROBLEM TO BE SOLVED: To enhance the degree of freedom in a setting design of a coil wound on an iron core and further, electromagnetic stirring capacity. SOLUTION: At a prescribed height position on the outside of one pair of long walls 2L, 2F faced to each other in a mold 1, the iron cores 3 for a linear motor are set in the width direction, respectively. In the coil 4 for the linear motor at the long wall 2L side, electric current is made to flow in U phase, -W phase, V phase, -U phase, W phase, -V phase, U phase, -W phase and V phase in order from the coil set at the end of right side in the attached Figure toward the coil set at the end of left side, respectively. Further, in the coil 4 for the linear motor at the long wall 2F side, electric current is made to flow in -U phase, W phase, -V phase, U phase, -W phase, V phase, -U phase, W phase and -V phase in order from the coil set at the end of left side on the attached Figure toward the coil set at the end of right side, respectively. The electric currents in the coils are circulated around the mold 1 while each phase is shifted by 60°counterclockwise. COPYRIGHT: (C)2004,JPO
