An amorphous core is a type of core that is made from an alloy of niobium or magnetized ferric. They are a type of core used in a variety of transformer devices. The most well known and widely used is the magnetic core. Their use is growing steadily because of their superior performance.
An amorphous core is made by manufacturing thin flat sheets of ferrous metal, which is also spun into a pattern by using a powerful magnetic field. Their thinness and small size have long been known to contribute to better electrical performance and less inductive losses. They are widely used in transformer systems for both the commercial and residential markets. Their use in residential devices has become more widespread due to their low cost and ability to create good sized wound induction coils. The use of amorphous core transformers slowly gained popularity, especially across China and India who have long were utilizing them for quite some time now.
They are designed for both the commercial and residential markets and come in a number of different sizes. Most are available in standard 4-inch size with some models available in six-inch size. Some models come with a special coating which helps resist short circuit and create smooth windings for easy installation. Some use a self-adhesive magnetic strip while others use pre-drilled magnetic strips. Regardless of the style, all amorphous core windings can resist short circuit and create smooth wound inductions.
The most common use for an amorphous core transformer is for the residential market. This can be used for anything from outdoor lighting systems to motion detectors. These are generally smaller than their metal counterparts and hence take up a smaller space. Many residential homes and offices have used them to replace large transformers as they find that they are cheaper and easier to install. However, in some cases it has been observed that the amorphous transformers create a smoother, cleaner and quieter signal than the metallic ones.
Another myth regarding the use of amorphous core is that they provide better load loss. This is because of a myth that metallic cables have a load loss of DC than amorphous cables do. It should be noted that both types of cables have DC load loss. The main difference lies in the way the voltage is delivered. Since the amorphous core does not conduct any electricity, it does not create any heat unlike a metallic cable and hence has no effects on the temperature of the surrounding.
Myth: The winding diameter of the cores increases the power. Amorphous cores are made using a variety of materials and the winding diameter depends on the material used. This means that if you are looking for high power you will have to opt for winding diameter of greater diameter. On the other hand, if you are looking for excellent performance and low power consumption then the winding diameter should be within 0.5 mm. The best quality cores are made using polyester or fiberglass with a core made of aluminum alloy. These cores are much lighter than other cores and hence they provide a better performance.
Myth: Single Phase cores create lower induced voltage. This is a myth because single phase cores have their own high power tolerance levels. This means that while they may have lower induced voltage they perform better than multi-phased cores. One important fact that can be understood through this is that while multi-phased transformers can tolerate a higher level of input voltage then single-phase transformers; the former have a much better output than the latter.
Myth: Core assemblies lead to improper power transfer. Again, this is a myth and is not true. It is a well known fact that the quality of a core assembly directly affects the performance and power of the core assembly itself. The two major power sources for a magnetic circuit are the permanent magnets and the non-permanent magnets. The inner core assembly connects both of them and thus it ensures proper polarity transfer throughout the whole process of transformer operation.
