Laminated Core Transformer Design

Laminated transformer core the core of a laminated transformer consists of a stack of punched sheet alloy made of iron and nickel the laminations.
Laminated core transformer design. However when a magnetic flux flows in a transformers steel core two types of losses occur in the. Transformers used for the distribution and control of electrical energy consist of a primary and secondary copper wound coil carrying a magnetizing current surrounding an iron core which is used for the transferring of power from the primary to the secondary coil. Electrical energy can be transferred between. A transformer is a passive electrical device that transfers electrical energy from one electrical circuit to another or multiple circuits a varying current in any one coil of the transformer produces a varying magnetic flux in the transformer s core which induces a varying electromotive force across any other coils wound around the same core.
The core is laminated to reduce these to a minimum as they interfere with the efficient transfer of energy from the primary coil to the secondary one. C i core a low cost solution to a new generation in transformer design. The eddy currents cause energy to be lost from the transformer as they heat up the core meaning that electrical energy is being wasted as unwanted heat energy. Most transformer cores are constructed from low carbon steels which can have permeabilities in the order of 1500 compared with just 1 0 for air.
