Customizing toroidal transformers is a wise decision. You may provide a detailed drawing specifying every element and aspect, or have the entire task outsourced. Then, you’ll only convey all the important information, and have everything right from designing to prototyping to manufacturing to testing taken care of by the manufacturer.
Planning on purchasing a toroidal transformer for your application? Check on for all the requirements and limitations first. Then, consider every pro and con of using the same for your application. Further, consider the configuration and mounting requirement. Only then should you approach any toroidal transformer manufacturers in India. Such careful consideration is important when you want to make the correct toroidal transformer choice.

Inductors are passive two-terminal electrical components that store energy in a magnetic field, when electric current flows through them. They generally consist of an insulated wire wound into a coil, around a core. Common mode chokes work as passive electronic inductors that filter out frequencies. High frequencies are specifically eliminated, while allowing low frequencies in …
Toroidal Transformer- Best Operation with Least Magnetic Field
Toroidal transformers are significant devices that are used for a wide range of applications in alternating current circuits. These passive electronic components are used as transformers or high-frequency coils. These transformers are considered as the highest performers amongst all the magnetic components of a system.
Efficient Designing: Toroidal transformers are designed in a way that a coil of insulated wire is wound up in a shape of a doughnut. The core is made of silicon steel, ferrite or other specialized material. This specific shape provides the transformer with greater efficiency compared to other conventional transformers of the same size. Coiling of insulated wire in toroidal shape also reduces the overall weight of this device. This effective designing has the advantage of greater power output at lesser weight. These transformers have large diameter and smaller number of windings, which helps reduce winding resistance. Also, toroids naturally retain their magnetic flux, which reduces losses due to stray magnetic flux. Core Material: Ferrite, silicon steel, MPP, Metglas, powdered iron, high flux kool mu or nickel steel can be used as core materials in the manufacturing of these transformers. Toroids can be built with UL recognized insulation materials. Many companies offer custom made toroidal transformer cores that can perform to meet specific client needs. Features and Specifications of Toroidal: These transformers are known to optimize the performance of an electronic device. They help in efficient dissipation of heat along with lowering the leakage inductance. Because of precise coil windings, there is lesser resistance and lowered winding losses. Toroidal transformers can be mounted in various formats such as PC mount bobbin headers, surface mount, vertical mount, and horizontal mount. Applications of Toroidal Transformers: These transformers can be effectively used in various products because of their small size and relatively lower maintenance requirements. Common facets where toroidal transformer can be used are clocks, time circuits, biomedical field, pneumatic systems, audio systems, power supplies, current transformers, chokes, pulse transformers, inductors, magnetic amplifier transformers, aeronautical applications, data processing and motor controls, computers, and other end-user applications. Advantages of Toroidal: Toroidal transformers have several advantages such as:
Portable Nature: Toroids are small in size as compared to their E-I transformer counterparts. Limited coil winding and compact designing makes these transformers very compact. Based on power rating, toroids are about 50% lighter as compared to the traditional laminated transformers. Smaller size and lighter weight makes this geometry highly portable.
Lower Mechanical Hum/Audible Noise: The coil of toroid is made of grain-oriented electrical grade silicon steel. This coil is tightly wound around core of the transformer and its sides are held in their places by welding them up. As there is no use of varnish or glue, there is lesser friction and the device operates silently without making any audible noise.
Greater Efficiency: The compact design and unique engineering of toroids make them around 15 to 30 per cent more efficient than conventional transformers. Their level of efficiency makes them a favorable choice in various electrical appliances across different fields.
Custom Designing and Dimensions: Different clients have different requirement of toroids based on their applications and nature of work. The dimensions of the core and the coil winding techniques can be tweaked based on these needs. Varying the height and/or the diameter of toroids to meet specific requirements also makes them flexible and economical for the client.
Decreased Magnetic Field Interference: Toroids are designed in such a way that there is a magnetic flux located into the core of transformer that helps in minimizing the magnetic field interference.
Easy Mounting: The toroids are designed in a way that they can be mounted easily without any expert guidance. A single center screw can be used to mount the device.
Toroidal transformers are excellent for efficient operation of a magnetic field. With a good brand and trusted manufacturer, one can get best quality toroid for their system.
