Ferrite

Ferrite Lapping is a process used to remove material from the surface of a workpiece, which is beneficial for creating a smooth finish after machining (removing any grooves or indentations). By creating a flat surface finish, Ferrite Cores can attain a tighter mating which increases AL value.

With increasing demands from power systems and electronic devices with electromechanical elements, such as the movement towards electric vehicles, power and signal transfer on rotating components is becoming increasingly important.

Gateway are excited to announce that we will be exhibiting at the PCIM show in Nuremberg, Germany – our team would love to see you there, so read on to find out more about what to expect!

The role of the Machining Apprentice is to work to support the day-to-day running of the machine shop.

The automotive industry is huge and the technology involved is constantly evolving from the initial “Benz Patent-Motorwagen” first presented in 1886 to the modern day Tesla Model 3 - a lot has happened and the technology involved is significantly different.

Ferrite sheets provide the benefits of traditional soft-magnetic materials whilst providing far more flexibility and versatility, freeing you from the typical mechanical constraints of Ferrite cores. Typically well suited for RFID and EMC protection due to its flexible nature and minimal material thickness (typically less than 0.2mm), Ferrite sheets can also improve the efficiency of wireless power transfer.

As industry evolves and has increasing demands on performance and speed of electronic systems whilst simultaneously reducing costs, these requirements are most noticeable when looking at power transmission. As technology advances a simple solution is actually the answer, using wiring harnesses is becoming a thing of the past and the use of busbars is paving the way for the future of lower cost and higher reliability.

Ferrite cores and single air gaps are very common as this technique of a single gap is able to delay the core saturation and as a results increase the cores performance. However its not all good as these relatively large single gaps cause higher fringing flux which will lead to additional copper losses in the windings, especially when operating at high frequencies. Now single gaps aren’t bad by any means as the pros out way the cons, however can we improve this technique even further and reduce the cons?

Ferrite.

From E cores to U Cores to EFD’s to RM’s we can source and modify these cores to bespoke tolerances and dimensions. But what if you could create your dream ferrite?

There are lots of manufactures out in the market who say they can undercut the market leaders on price, and even though this may seem to be the most cost-effective option on the day, is that the actual cost that you will pay as a business?
