PURPOSE: To simplify repair by composing an inductor for an electromagnetic trough of a plurality of units, separately constituting each unit through concentrated winding to a core with salient poles in the multiple of three and executing three-phase connection for generating a shifting field.
CONSTITUTION: When three-phase AC voltage is applied to each coil 2c1, 2c2, 2c3 for respective inductor unit 2b1∼2bn so as to generate a shifting field in the direction of carrying of a molten metal Q, magnetic flux bridges among the pole faces of the salient poles 2c1, 2c2, 2c3 for each unit 2b1∼2bn in an inductor 2b composed of a series of respective unit 2b1∼2bn, and the magnetic flux shifts toward the direction that the proceeding of the molten metal Q is accelerated. When the coils are damaged, only the inductor unit to which the coil belongs is exchanged, thus simplifying repair.
