What is stacking factor of magnetic cores?
Magnetic cores are made up of thin ,lightly insulated ( coating of varnish ) laminatians to produce power loss in cores due to eddy current phenomenon . as a result ,the net cross sectin area of the core occupied by the magnetic material is less than its grosss cross section ; their ratio ( less than unity ) is known as stacking factor . depending upon the thicknesss of lamination ,stacking factor vary from 0.5 to 0.95 approching unity asthe lamination thickness increase
What are the two parts of the core?
the two parts of the core are the inner core and the outer core
Which one comes first the inner core or the outer core?
The outer core comes before the inner core. The Earth's structure consists of the inner core, outer core, mantle, and crust. The outer core is a layer of molten iron and nickel that surrounds the solid inner core.
What are the two layers of earth's core?
The two layers of Earth's core are the outer core and the inner core. The outer core is composed mainly of liquid iron and nickel, while the inner core is a solid sphere made of iron and nickel.
How is the inner core and outer core different from each other?
The outer core is liquid, the inner core is solid The outer core surrounds the inner core The outer core is iron-rich, the inner core is iron-rich and nickel-rich There is more pressure acting on the inner core The inner core is hotter
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.
Why is the core is laminated alternatively in motor?
Cores are laminated to reduce circulating currents, called 'eddy currents', which are caused by voltages induced into the core. As each lamination is effectively insulated from its neighbours, its cross-sectional area and, thus, its resistance is increased. Additionally, the voltage induced into each lamination is much lower than would be induced into an unlaminated core -so, the combination of lower induced voltages and higher resistances significantly reduce energy losses in the core.
Why pet film used for lamination?
its good for lamination
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.
What is the value of a 2008 New Mexico quarter that is half copper on the heads side?
This is a common error called a lamination error. It occurs when part of the copper-nickel outer cladding doesn't stay bonded to the inner copper core. Lamination errors on state quarters retail in the $10 range.
How is eddy current related to the thickness of the stampings of core?
A: Eddy currents are current losses if an iron bolt is used to hold the core lamination together that alone will cause losses. Usually a brass bolt is used to eliminate 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.
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.
Is there a cover you can put over your laptop screen so it is not so bright and not such a strain on your eyes?
You can use a tinted lamination from any place where they stick lamination on windscreens in automobiles who use dry lamination.
What factors could affect an eletromagnets strength?
The number of windings around the core. The power available to the coil. The temperature of the unit.De-lamination of the windings. The wrap needs to be tight and uniform. Stupidity.
What do you call gluing wood pieces parallel to each other?
Lamination is the gluing together of sheets of wood .
What is theMethod of lamination for flexible packaging?
Dear friend , The techniques used for lamination can be classified on the basis of adhesive system used. The most common lamination techniques are · Wet lamination - By using water based adhesives · Dry lamination - By using solvent based or solventless adhesives · Hot melt or wax lamination - By using wax or polymers like polyethylene, polyamides etc. · Extrusion lamination - By extruding polymers between two substrates In packaging industry, solvent-based & solvent free adhesives are commonly used for most of the flexible laminates .
