The laminated plates prevent eddy currents from forming and thus creating unwanted magnetic flux which would counter the flux needed to induce the electric current in the secondary coil

I need to make a 72VA 220-12V DC Transformer. The drawing gives me 158 lamination and I need to use 133. How do you convert a 158 lamination to 133 lamination?
There is no such thing as a 'd.c. transformer'. If this is a typo, and you really mean an 'a.c. transformer', then the number of laminations will act to reduce the eddy-current losses within the core, but should not affect the turns ratio of your transformer if that's what you are trying to achieve.
Which material is used for transformer lamination?
low carbon steel
How do you reduce core losses?
There are various measures that can be taken to reduce core losses. Lamination of the transformer core is believed to reduce core losses significantly.
Is there an available method for an experiment to show that the output of a transformer is dependent on lamination?
The output of a transformer is NOT dependent on laminations. It is dependent upon the turns ratio and input voltage and current. The core of transformers is often laminated to minimize eddy currents - currents that don't flow in the desired direction, and cause extra heating in the transformer (minimizing lowers the amount of losses in the transformer).
Why pet film used for lamination?
its good for lamination
What is dielectric test in transformer?
why need dielectric test for transformer
Transformer Output power less than input power?
A: Absolutely a power transfer will have an internal loss of IR . for a power transformer the loss can be as much of 20% or more if other magnetics are involved like iron screw holding the lamination together. Usually brass is used to reduce that loss.
What are uses of transformer's lamination?
Presumably, you are asking "What is the function of transformer laminations?", rather than their "uses".A transformer's magnetic circuit, or core, is made from thin sheets of silicon steel, each insulated from each other, and termed laminations.The alternating current flowing through a transformer's primary winding not only induces a voltage into the secondary windings, but into the core itself, resulting in circulating currents, called eddy currents, which result in energy losses. The very low cross-sectional area of each lamination acts to offer a high resistance to the flow of these eddy currents, thus minimising these currents, and the associated eddy-current losses.
What are cold lamination machines?
Cold lamination machines offer an alternative method of lamination by using adhesives instead of heat. As opposed to traditional thermal machines, cold lamination machines are significantly less expensive and will not damage materials vulnerable to heat.
Why need to vacuum in transformer chamber before filling transformer oil and how long need to vacuum?
we need vacuum to remove moisture from tank
What websites sell laminator pouches?
A laminating pouch is a lamination-plastic sleeve that a sheet of paper or other thin object can be inserted in, to allow easy lamination using a home lamination machine. Amazon sells laminating pouches, as does a site called Lamination Depot.
Does a transformer changes the frequency of incoming supply?
Yes the transformer effects the incoming frequency supply. This frequency is dependent on the core lamination of the transformer the weightier the core lamination the lesser will be the frequency we get and vice verse..
