Products Description
Our Relay Armature pure iron plate is a crucial component designed specifically for the demanding requirements of relays, especially those used in Electric Vehicles (EVs). It is meticulously crafted to ensure optimal performance and reliability in electrical switching applications. The use of high-quality electrician pure iron as the base material gives it excellent magnetic properties, making it an ideal choice for efficient relay operation. This pure iron plate is the result of advanced manufacturing techniques, such as Electrical Pure Iron Stamping, which allows for precise shaping and customization to meet the specific needs of different relay designs. Whether it's for the core, yoke, or armature of a relay, our pure iron plate plays a vital role in enhancing the overall functionality and durability of the relay system.
Product Parameters
Magnetic Permeability
Ranges from 800 to 1200 μ (microhenries per meter) depending on the specific grade and treatment of the pure iron. This high permeability enables efficient magnetic flux conduction, reducing energy losses and improving the relay's response speed.
Saturation Magnetic Flux Density
Typically reaches around 2.0 to 2.2 Tesla. This property ensures that the armature can handle high magnetic fields without saturating, allowing for reliable operation even under heavy electrical loads.
Electrical Resistivity
Approximately 9.71 x 10^-8 Ω·m. This relatively low resistivity helps in minimizing power dissipation due to eddy currents, further enhancing the efficiency of the relay.
Plate Thickness
Available in standard thicknesses of 0.5 mm to 2 mm, with a tolerance of ±0.05 mm. This precise thickness control is crucial for maintaining the proper air gap and magnetic circuit characteristics within the relay.
Pure Iron Cold Rolled Steel for Relay Core, Yoke, and Armature
The pure iron cold rolled steel we use is sourced from reliable suppliers and undergoes strict quality control. It is characterized by its uniform microstructure, which contributes to its excellent magnetic and mechanical properties. The relay core, provides a stable magnetic path, reducing magnetic leakage and improving the overall magnetic efficiency. In the yoke, it helps in distributing the magnetic flux evenly, enhancing the magnetic coupling between different parts of the relay. And for the armature, its high ductility and magnetic responsiveness ensure smooth and reliable movement during relay operation. The cold rolling process further refines the grain structure, increasing the strength and hardness of the steel while maintaining its good magnetic properties.
Relay Armature Details
The EV Relay Armature is designed with precision-engineered features. The surface of the pure iron plate is carefully finished to ensure a smooth and flat contact surface, minimizing friction and wear during operation. The edges are rounded and deburred to prevent damage to other components and to ensure safe handling. The armature is often stamped with specific patterns or grooves to optimize the magnetic field distribution and enhance its magnetic holding force. Additionally, it is designed to have the appropriate mass and inertia to ensure a quick and accurate response to the electromagnetic force generated by the relay coil.
