Products Description
As the core moving component of an electromagnetic relay, the EV Relay Magnetic Armature drives the contacts to perform opening and closing operations via electromagnetic force, which is key to the power control capabilities of high-voltage DC relays. Made from electric pure iron, it possesses excellent soft magnetic properties and mechanical stability, making it suitable for high-voltage DC applications such as new energy vehicles, charging piles, and energy storage systems. Manufactured in our own factory, we support both standardized product supply and customized development, meeting the design and production needs of high-voltage DC relays of various specifications.
Technical Advantages
Stable Performance
By adopting standardized production processes and quality control procedures, the magnetic and mechanical properties of the Pure Iron Armature for EV Relay exhibit high batch-to-batch consistency, thereby reducing defect rates in customer production.
Reliable Lifespan
Verified through multiple fatigue tests, the Precision Stamped EV Relay Armature maintains stable performance even after millions of operating cycles, reducing after-sales failure rates for customer products.
Precise Dimensions
A high-precision stamping process with strict control over key dimensional tolerances ensures good compatibility with other components of the customer's relays, thereby reducing assembly and debugging costs.
Strong Compatibility
Supporting various surface treatments and structural designs, the Movable Armature Plate for EV Relay is adaptable to high-voltage DC relays with different operating environments and load requirements.
Detailed Display and Structural Disassembly
Armature Body
The Relay Armature Plate is a flat or U-shaped structure with uniform thickness and a central riveting hole or positioning boss for assembly with the moving contact assembly.
Magnetic Contact Surface
The bottom surface of the Soft Magnetic Armature for EV Relay is the magnetic contact surface that mates with the yoke. The surface roughness Ra ≤ 1.6μm ensures minimal air gap when the magnetic circuit is closed.
Terminal Lead-Out Section
Conductive terminals extend from both sides of the Relay Terminal Armature. The terminal heads are equipped with connection holes (round or oblong) for crimping terminals or bolt connections.
Insulation Structure
A flanged insulating wall or ceramic/plastic isolator is installed between the armature and the terminal to form effective electrical isolation.
Application Scenarios
