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 […]

Introduction: Why Core Laminations Matter for Transformer Performance In today’s competitive transformer-component market, the quality, precision, and engineering of the core laminations play a vital role in achieving high-efficiency, reliable, and cost-effective transformer solutions. As a dedicated supplier of EI transformer cores, Tianxiang understands that the heart of any transformer’s magnetic circuit is composed of stacked sheets

Designing a high-performance transformer begins with careful attention to the core structure. Among the many decisions that shape efficiency, reliability, and long-term performance, one of the most fundamental is how the laminations are assembled. Two common manufacturing methods stand out: stacked riveting and butt stacking. Each approach has its own structural logic and practical implications,

In power transformers, small material decisions can have outsized impacts on long-term performance. Among these decisions, annealing of transformer cores is one of the most critical yet often underestimated steps in manufacturing. Proper annealing directly affects magnetic properties, core losses, noise levels, and overall transformer efficiency. For manufacturers, utilities, and industrial users seeking reliable and

In modern power systems, transformers are expected to deliver high efficiency, long service life, and stable performance under increasingly demanding operating conditions. Among the various factors that influence transformer efficiency, core loss remains one of the most critical—and often underestimated—contributors. Core loss not only reduces overall efficiency but also leads to excessive heat generation, higher

When engineers and manufacturers begin evaluating materials for a silicon steel transformer core, one of the most critical decisions is choosing between CRGO vs CRNGO. These two categories of electrical steel—Cold-Rolled Grain-Oriented (CRGO) and Cold-Rolled Non-Grain-Oriented (CRNGO)—are the foundation of modern electromagnetic devices. Understanding how they differ, how each influences transformer performance, and when to use one

The manufacturing of EI laminations is a crucial process in the production of transformer cores. EI laminations, often made from electrical steel, are fundamental in minimizing energy losses and improving the efficiency of transformers. This article provides a detailed overview of the EI lamination process, from the initial punching of sheets to the final stacking of laminations.
