For engineers and sourcing teams working with transformers, inductors, reactors, and power electronics, EI lamination with air gap is an important core structure to understand. Unlike a standard EI core, a gapped EI core includes a controlled air gap in the magnetic path. This air gap helps manage magnetic saturation, stabilize inductance, and support specific […]

For engineers, sourcing teams, and OEM buyers, burr control in silicon steel laminations is more than a small manufacturing detail. Burr height, edge cleanliness, stamping accuracy, and stacking quality can directly affect transformer core loss, motor core assembly, noise, insulation reliability, and long-term electrical performance. When buyers compare silicon steel lamination suppliers, price and lead

For engineers, purchasing managers, and OEM sourcing teams, transformer core performance is not determined by material grade alone. The way silicon steel laminations are processed after stamping can also affect magnetic stability, core loss, noise, heat rise, and long-term reliability. One of the most important processes is annealing transformer cores. Annealing is a controlled heat

Getting an accurate quote for custom silicon steel laminations is not only about sending a part name and asking for a price. For transformer cores, motor cores, reactors, inductors, and other magnetic components, small details in the drawing, material, thickness, stacking method, and performance requirements can change the manufacturing process, tooling cost, lead time, and

For transformer, reactor, inductor, and power supply applications, choosing the right laminated core structure can affect electrical performance, assembly efficiency, material cost, noise level, and long-term reliability. Two common options are EI lamination and UI lamination. Both EI and UI laminations are made from silicon steel or electrical steel and are widely used in magnetic

For transformer manufacturers, power supply engineers, and OEM sourcing teams, core loss in transformer laminations is one of the most important factors affecting efficiency, heat rise, noise, and long-term reliability. A transformer core may look simple from the outside, but small differences in silicon steel grade, lamination thickness, stamping quality, burr control, stacking method, and

Choosing the right silicon steel lamination thickness is one of the most important decisions in transformer core design and sourcing. Thickness affects core loss, efficiency, heat rise, noise, stacking height, material cost, manufacturing difficulty, and final product performance. For transformer manufacturers, power supply engineers, and OEM buyers, the question is not simply whether thinner silicon

For motor manufacturers, appliance brands, industrial equipment suppliers, and OEM sourcing teams, the motor stator and rotor core is one of the most important parts of an electric motor. The core structure, material grade, lamination thickness, slot accuracy, burr control, stacking quality, and final assembly can all affect motor efficiency, noise, vibration, heat rise, and

As the global automotive industry accelerates toward electrification, a critical yet often overlooked component is taking center stage in innovation and performance: the EV motor core. This essential part lies at the heart of electric vehicle (EV) propulsion systems, influencing everything from energy efficiency to driving experience. But what exactly makes the EV motor core so
