Grooved Core For AC Relay
Products Description
The Grooved Core for AC Relay is one of the most critical magnetic circuit components inside an AC relay. It undertakes the core functions of magnetic flux transmission, magnetic field stabilization, and enhanced attraction, ensuring the relay's rapid response, stable engagement, and low-noise operation.
Our company utilizes high-performance silicon steel sheets and precision stamping, combined with optimized slot structure, to achieve higher magnetic circuit utilization, significantly reduce AC hysteresis noise, and improve overall reliability. This type of product is widely used in:
Power automation equipment
Industrial machinery control systems
New energy storage and inverter control
Elevator and crane control systems
Home appliances and general AC relay production
We provide a full-process supply capability, from structural development → mold design → stamping manufacturing → precision machining → surface treatment → component support, suitable for large-volume and OEM customization.
Main Functions: Addressing the Core Pain Points of AC Relays
Directional Magnetization Function
The slotted structure and directional magnetizing material work together to guide magnetic lines of force along the slot, reducing leakage flux by over 18% and increasing magnetic energy utilization by 25%. This ensures sufficient relay engagement force and precise operation, preventing weak engagement due to leakage flux.
01
Low Power Frequency Consumption Function
The combination of low-loss silicon steel for power frequency and optimized processes reduces the total loss of the AC Relay Core and Copper Ring by 25% at 50/60Hz, minimizing energy waste during AC relay operation. This aligns with the energy-saving requirements of home appliances and industrial equipment, reducing user costs.
02
Low Noise Operation Function
The slanted slot design and rounded tooth treatment work together to achieve operating noise ≤45dB, meeting the quiet requirements of home appliances and office equipment while preventing noise-induced equipment resonance and component fatigue.
03
Coil Adaptation Function
Customized slot dimensions and optimized inner wall design accommodate coils of different wire diameters and turns, improving coil fixation firmness by 40%. This prevents magnetic circuit misalignment and poor contact caused by AC Rod loosening during long-term operation, extending relay lifespan.
04
Temperature Rise Suppression Function
The oil guide groove design, combined with low-loss characteristics, reduces the operating temperature rise of the Core AC and coil. Under-rated load, the temperature rise is ≤45K, preventing coil aging and insulation failure caused by high temperatures and ensuring long-term stable relay operation.

Design Advantages: Engineering Thinking from Microscopic to Systematic Perspective
Deep Integration of Slot Structure and Relay
The slot DT4C AC Relay Iron core CNC lathe processing design is not isolated but deeply integrated with the entire relay system. The shape, depth, and distribution of the slots are optimized through system-level electromagnetic simulation to ensure optimal performance across different relay designs, avoiding performance losses caused by design mismatches in traditional cores.
Optimized Installation Ease
Microscopic guide marks on the AC Core for Industrial Relay surface allow installers to visually determine the correct installation position. The installation process is simple and intuitive, reducing installation errors, improving production efficiency, and ensuring precise alignment of the magnetic circuit.
Engineering Compatibility with Universal Interfaces
The design conforms to industry-standard interfaces, enabling seamless integration with mainstream relay designs, reducing system modification costs, and improving overall installation efficiency. Interface dimensions are precisely calculated to ensure consistent performance across different brands of relays.
