قلب المحول

It is core type, manufactured from silicon alloy sheet steels like M5, M4, M3, MOH and ZDHK with directed crystal- line orientation (grain-oriented) and having thicknesses of 0,30 mm, 0,27 mm and 0,23 mm. The sheet steel cut to a mitered form of 45 degrees angle at the section where the magnetic flux passes are slitted into intended shape and stacked with CNC slitting machine and packed to form a magnetic circuit. Cutting and packing operations for magnetic circuit are handled with a method known as step-lap which reduces iron losses to a minimum. The core is package by applying step-lap method both crosswise and lenghtwise.

The cross sections of leg and connecting cap pieces are the same and multistepped and theoretically it is assumed to be round cross section.

Core laminations, U-core and connecting cap piece are so compacted by way of steel studs passing through insulated bushings that noise of them are kept minimum.
