Precision Stamping EV Relay Core
Products Description
Produced through multiple precision stamping processes, the Precision Stamping EV Relay Core is a core magnetic circuit component dedicated to high-voltage relays in new energy vehicles. The precision stamping technique allows this component to strike a balance between high-precision dimensions and stable magnetic permeability. Made from high-purity electric pure iron, it meets the stringent magnetic circuit requirements of new energy vehicle high-voltage relay systems. Suitable for relays in a variety of high-voltage applications, including main circuits and charging circuits, it offers a low-reluctance, high-efficiency magnetic circuit path for the electromagnetic system.
Product Features and Functions
Optimized Magnetic Circuit Structure Design
With a T-shaped or I-shaped flat cross-section, the Flat Core for EV Relay delivers improved magnetic circuit performance. Electromagnetic simulation was employed to optimize the cross-sectional area of the magnetic circuit, leading to reduced reluctance and increased flux density. This allows the relay to achieve stronger electromagnetic attraction without changing coil parameters.
Multi-Layer Stacked Structure
Some versions of the Stamped and Formed Relay Core use a laminated stack design. Electrical isolation between the stacked layers is maintained through an insulating treatment, which dramatically cuts eddy current losses under high-frequency conditions. This improvement boosts the relay's operational reliability in PWM modulation environments.
Precision Positioning Holes
The High Voltage EV Relay Flat Core Stamping Part features pre-cut precision-stamped positioning holes and bending reference surfaces, ensuring a precise fit with the relay coil frame and yoke. This guarantees a uniform and controllable air gap in the magnetic circuit, preventing magnetic circuit misalignment or abnormal engagement noise caused by assembly deviations.
Corrosion-Resistant Surface Treatment
Optional nickel plating, zinc plating, or phosphating treatments are available. Salt spray testing can reach over 96 hours, meeting the high-temperature, high-humidity, vibration, and chemical corrosion requirements of the engine compartment and chassis areas of new energy vehicles.
