Stamping Core For New Energy Relay
Products Description
The Stamping Core for New Energy Relay of the new energy relay is a key magnetic component designed specifically for new energy power conversion scenarios. As the core component of the relay's magnetic circuit system, it focuses on three core requirements: efficient magnetic energy conversion, extreme environment tolerance, and precise structural adaptation. Through customized magnetic material selection, precision stamping, and magnetic performance optimization processes, it solves the pain points of traditional iron cores in new energy scenarios, such as insufficient magnetic permeability, excessive iron loss, significant temperature drift, and poor structural compatibility. The product is widely used in new energy vehicles, energy storage systems, photovoltaic inverters, charging piles, new energy ships, and other fields with stringent requirements for magnetic circuit efficiency, stability, and lightweight design. It is a "key energy conversion carrier" that ensures the relay's rapid response, low-power operation, and long service life.
Functional Essence: Electromagnetic Energy "Converter" and "Controller"
High Magnetic Permeability
Utilizing specially oriented silicon steel sheets, the uniformity of magnetic flux density is increased by 30% compared to ordinary EV Relay Cores, reducing leakage flux loss.
Low Eddy Current Loss
Ultra-thin silicon steel sheets (thickness ≤0.2mm) combined with an insulating coating reduce eddy current heating by 40%, making Flat Core for EV Relay suitable for high-frequency switching applications.
Strong Anti-Saturation Capability
Through optimized magnetic circuit structure, Stamping Iron Core Bending Part for EV Relay maintains stable magnetic characteristics even at 120% of rated current, avoiding the risk of contact sticking.
Detailed Showcase – Quality Verified from a Professional Perspective
Observe the Lamination Cross-Section
The laminations of the Pure Iron Core for EV Relay are neatly stacked, without misalignment or gaps. The riveting points are evenly recessed, with no cracks or deformation around them.
Touch the Edges and Surface
Gently run your hand along the edge of the core material for electromagnet; you will not feel any burrs. The surface coating is uniform, without peeling or scratches.
Examine Dimensional Consistency
Randomly select several finished iron coils and measure them using calipers or a projector. You will find that the dispersion of key dimensions (such as pole shoe width, total thickness, and rivet hole positions) is extremely small, demonstrating superior craftsmanship.
Reliable "Silent" Performance
Assemble our electromagnet cores into relays for testing. You will hear a crisp and powerful "click" when they engage, feel no excessive vibration, and the operating temperature rise is significantly lower than that of conventional products on the market. This is the best proof of its high efficiency and low loss performance.
