Why laminations are used for making transformer What is the thickness of lamination and why?

What is the thickness of lamination used in a transformer?

Detailed Solution

The transformer core is generally made of thin strips called laminations to reduce eddy current loss. The thickness of the transformer core laminations is usually in the order of 0.25 mm to 0.5 mm.

What is the purpose of laminations?

Lamination increases the durability of print materials, allowing them to withstand frequent use. Lamination adds protection against fingerprints and smudges, stains and spills, tears and wrinkles, marks and abrasions, plus oil, grease, dirt, moisture and other contaminants.

Why the transformer core is made of thin laminated ferromagnetic material?

Iron core is thin & laminated in transformer to avoid the loss of eddy current. Eddy current is induced in core and circulates normal to the width of the core causing heat.

Why stator core is laminated?

During the process of induction heating, the bearing heats up quite quickly while the cross bar stays relatively cool. Simply stated a stator core is laminated and insulated in order to reduce induced circulating currents and associated heat down to a manageable level.

What is the thickness of laminations used in a transformer * 1 point?

Basically, these steels are alloys of Fe-Si and they are laminated materials having a thickness of less than 0.5 mm; for transformer usually the thickness is in the range of 0.18 to 0.27 mm [1].

What is laminated plastic?

: a plastic made of superposed layers of paper, wood, or fabric bonded or impregnated with resin and compressed under heat.

What are laminations in a laminated iron core?

Laminated magnetic cores are made of stacks of thin iron sheets coated with an insulating layer, lying as much as possible parallel with the lines of flux. The layers of insulation serve as a barrier to eddy currents, so eddy currents can only flow in narrow loops within the thickness of each single lamination.
