Background

The magnetic force is often increased by using the iron core in the transformer, but the iron core is often in a sheet shape because the sheet-shaped iron core can reduce eddy current loss. When the transformer is in operation, the coil has an alternating current, and the magnetic flux generated by the alternating current is of course alternating. This changing magnetic flux generates an induced current in the core. The induced current generated in the core flows around in a plane perpendicular to the direction of the magnetic flux, and is called eddy current. Eddy current losses also cause the core to heat up. In order to reduce eddy current losses, the core of the transformer is laminated with silicon steel sheets insulated from each other, so that the eddy current passes through a smaller cross section in a long and narrow circuit to increase the resistance on the eddy current path. The iron core thickness is minimum, and the machining precision is high, consequently when cutting the iron core, need fix the iron core, if the centre gripping is unstable, causes processing production safety problem easily.
