Like every transformer type, toroidal transformers are designed to change AC current without any type of movement or manipulation of components. However, what sets it apart is that its toroidal core is made of cold-rolled silicon steel, increasing the performance of the core compared to any other traditional laminated core. A coil that generates magnetic lines of force is wound on the iron core, which completely coincides with the magnetic circuit of the iron core. This results in reduced excitation energy and core losses. Hence, toroidal transformers benefit the application by providing high electrical efficiency and less magnetic interference, small in size which also makes them absolutely light in weight.

　　Here are five reasons why toroidal transformers are used in many industrial applications:

　　Low Noise and Low Stray Fields - Due to the uniform winding of the magnetic core, the fields generated by the magnetization (also known as stray fields) are low in toroidal transformers. The less magnetic interference in the toroid, the better the performance.

　　EASY INSTALLATION - The toroidal transformer can be easily installed in a short time using only one screw. This convenience helps reduce maintenance and downtime.

　　Low Operating Temperature - Toroidal transformers operate cooler than transformers with similar specifications.

　　Lightweight Iron Core - The iron core of a toroidal transformer is lighter than a typical transformer because it consists of fewer raw materials.

　　More Economical - Because toroidal transformer cores are made of less material, they weigh less and use less energy than traditional transformers, resulting in better cost savings and a higher return on investment.
