Transmitter Coil Assembly

The Transmitter Coil Assembly is a critical electromagnetic component within an Industrial System that generates oscillating magnetic fields or transmits electrical signals through inductive coupling. It serves as the active transmitting element in systems requiring wireless power transfer, proximity sensing, data communication, or inductive heating by converting electrical energy into controlled electromagnetic radiation. The assembly typically consists of a wound copper wire around a ferrite core, with the coil geometry and winding pattern determining the field characteristics, efficiency, and operating frequency range. It is designed for use in computer, electronic, and optical product manufacturing, where it may be integrated into larger systems for energy transfer or signal transmission. The assembly operates within specified electrical parameters, including a rated power of 50–500 W, an operating voltage of 12–48 V DC, and a current consumption of 1–10 A at rated power. Its inductance ranges from 10–100 mH at 1 kHz, and its DC resistance is 0.5–5 Ω. The insulation resistance is at least 100 MΩ at 500 V DC, and the dielectric strength is 1500 V AC for 1 minute, both tested per IEC 60243. The operating temperature range is -40 to 85 °C, with storage from -40 to 105 °C. The assembly is rated IP54–IP65 for dust and water resistance per IEC 60529. The coil wire is enameled copper (Cu) per ASTM B3, and the core is high-permeability ferrite. The weight varies from 0.5 to 2.5 kg depending on size. These values are reference ranges and must be confirmed for the specific model and application. The assembly is a component, not a standalone product, and its performance depends on the system design and operating conditions. For procurement, verify model-specific values and standards with the legal manufacturer or supplier.

When electrical current flows through the wound conductor of the coil assembly, it generates a time-varying magnetic field according to Ampère's law and Faraday's law of induction. This electromagnetic field propagates through space or couples with nearby receiver coils, enabling energy transfer, signal transmission, or inductive effects without physical contact. The assembly's physical construction (coil geometry, winding pattern, core material) determines the field characteristics, efficiency, and operating frequency range.
