Comparing Toroidal Transformations and Other Transformers

It is obvious when you look at a toroid because it has a very specific shape. The 360-degree, doughnut-shaped core is made from ferromagnetic materials (iron powder, laminated iron, and more). The devices then go through custom coil winding before it is ready for use. Toroidal transformers are used within various applications that include power supplies, amplifiers, and inverters. In many cases, engineers choose toroidal transformers and custom coil winding over other conventional transformers.Custom Coil Winding

SIZE

When compared to a standard transformer of similar power, a toroid is both smaller and lighter than its counterpart. Because toroid coil winding requires the least amount of materials, it is considered an ideal shape. Toroid coil winding is evenly spread out over the entire core, which reduces the length of the wire. It is typically easy for engineers to fit toroids into compact designs without having to make many changes.

EASY MOUNTING

The small, circular shape of a toroid means that it can be mounted with only a single center bolt. Mounting a toroid is quick and easy, and it does not get in the way of the custom coil winding. A standard transformer requires at least four screws.

LOW NOISE

Traditional transformers are typically loud, but that is not the case when using toroidal transformers. Their core winding adds an extra layer that vibrates between the core laminations and coil turns. That vibration causes an audible hum that comes from the transformer. Custom toroid winding is uniform and leaves no air gaps. There are no loose sheets that vibrate and make noise. You may hear a slight hum when power is first turned on, but it will quickly die down after a few seconds.
