Understanding the complexities of toroidal transformers can be difficult, especially because they come in different systems and are used in a wide variety of applications. Although we approach each project on a one-on-one basis, there are similarities between winding, materials, and cores. Below, we have compiled a small list of frequently asked questions about toroidal transformers.
What applications are best suited for toroids?
These transformers are used with any electronic transformer application that can house the shape of a toroidal transformer. A toroid is not always the most appropriate transformer, but they can be used in almost all electronic applications.
Do toroidal cores come in different materials?
We work with any available material, but we commonly work with:
- Silicon steel
- Molypermalloy powder
- Nickel iron
- Iron powdered
- Ferrites
- Amorphous
For more information on what characteristics each material offers, please do not hesitate to give our team a call.
Why are toroids shaped like doughnuts?
Utilizing a full 360-degree wound transformer allows for better symmetry because of its circular shape. Perfect symmetry offers users a near completed magnetic field cancellation that is outside of the coil. This means that the toroid will have significantly less leakage inductance and lower EMI radiation when compared to other transformers of similar power ratings.
What are gapped toroidal transformers?
These toroids have their gaps filled with a type of insulation material that helps to facilitate the winding process.
Is it possible to create non-magnetic cores?
Simply put, yes. Depending on your specific needs, we can build custom toroids to fit specific needs and applications.
Does Torelco build encapsulated toroidal transformers?
Yes, we can. Our shop is equipped with the necessary tools and materials to make fully encapsulated transformers, which are amongst the best toroids on the market.
