How Do Automatic Core Winding Machines Affect Transformer Cores
The core is the heart of any transformer and the manufacture of these cores through the use of automatic core winding machines is key to producing top quality and efficient transformers.
When we think of transformers usually the first thing that comes to mind is the distribution transformers that we see often high up on hydro poles that are used for the distribution of electricity. Aside from that, transformers are also present in small machines that are capable of transferring electrical current in circuits with the use of the principle of electromagnetic induction..
In order for electricity to function well, the various parts of a transformer work together to allow the power to effectively flow. The core or "wound core" to be precise makes up the majority of the transformer and thus why having an effective core is the most important part of any transformer.
There are primary, secondary and sometimes there could be tertiary windings. How well the transformer performs is determined by the magnetic flux between windings. For the most efficient flux between these windings, a single low reluctance magnetic path is required. The core provides this low reluctance path.
Generally, there are different types of cores -- solid, steel laminated, air and toroidal wound cores.. Among these choices, your budget and personal preference determines the kind of wound core you will purchase for your transformer.
Cores That Are Steel Laminated
These cores are good for transmitting at the audio frequency level due to their high permeability. On the other hand, a core which is not laminated tend to suffer from overheating and greater levels of loss in electrical current. The two major structures of steel laminated cores are the C and E-shaped core, respectively.. Out of the two, E-shaped cores are more cost-effective but also have greater tendencies of losing electrical energy because of their structure. The C shaped is better as the grains runs parallel to the flux yet tend to be more expensive.
Cores That Are Solid In Form
Highly recommended for transmissions that require higher frequencies, solid cores are most effective because of their powdered iron form.. However, for even greater frequencies, ferrites are utilized as better counterparts of powdered iron content.
The most versatile as a variety of material would be used such as steel, powdered iron or ferrites. Mostly circular in shape, toroidal cores leave no spaces for air or materials with long forms can be utilized. This is important since materials with longer strips and forms bring with them an even lesser amount of resistance. The windings of toroidal cores are wrapped around its central core, giving it an impression of an inter-winding wrap around a circular base.
Air Core Forms
As the name suggests, these cores utilizes the magnetic property of air in its electrical circuit. However, because the leak of energy is surmountable high, air cores are not commonly used.
High quality automatic core winding machines are critical to produce effective and efficient transformer cores. In fact, these winding machines that create continuous winding patterns in cores are more effective compared to those that produce otherwise. The consistency in the gap patterns as well as the capacity to create different patterns are characteristics of excellent winding machines that produce top quality transformer cores.
You can greatly save money by paying for good quality transformer cores made by reliable core winding machines http://tranco.ca/quality-counts-in-transformer-core-winding/ compared to low-budget transformer cores, especially if you are looking for the ones that are sure to last for a long time.
