This industrial wireless power transfer module is a standardized component designed for integration into industrial equipment and machinery. It enables contactless power delivery to moving parts, rotating assemblies, or sealed enclosures where traditional wired connections are impractical. The module operates via electromagnetic induction between transmitter and receiver coils, converting electrical energy to magnetic fields and back to electrical energy without physical contact. It features robust construction for harsh industrial environments, with protection against dust, moisture, and electromagnetic interference. The module supports various industrial communication protocols for power management and monitoring. Key specifications include a continuous power rating of 100–500 W, DC input voltage of 24 V ±10%, regulated output voltage of 24–48 V, operating frequency of 85–90 kHz (referenced to IEC 62827-2), typical efficiency at rated load of ≥90%, maximum air gap of 10–25 mm, transmitter coil outer diameter of 80–120 mm, ingress protection rating of IP54–IP65 (referenced to IEC 60529), communication interfaces RS485 and CAN, operating temperature range of -20 to 60 °C, storage temperature range of -40 to 85 °C, relative humidity of 5–95% non-condensing, transmitter module dimensions of 150×100×40 mm, and transmitter module weight of 0.5–1.0 kg. Materials used include ferrite core, litz wire coil, aluminum housing, thermal interface material, and FR4 PCB. This module is intended for design engineers and maintenance professionals who need to integrate wireless power into industrial systems. When selecting or verifying a specific model, always confirm model-specific values and standards with the legal manufacturer or supplier, as the listed parameters are reference ranges for the product category. The module is not a complete power supply; it requires appropriate control circuitry and protection. Proper alignment and air gap within specified limits are essential for efficient operation. The module is not certified for any specific application unless explicitly stated by the manufacturer; standards referenced are for verification purposes only.
The module uses electromagnetic induction between a transmitter coil and a receiver coil. An alternating current in the transmitter coil generates a time-varying magnetic field. This field induces an alternating voltage in the receiver coil, which is then rectified and regulated to provide DC power. The coils are typically wound with litz wire to reduce losses, and ferrite cores concentrate the magnetic flux. The system operates at a resonant frequency of 85–90 kHz to improve efficiency. Power transfer occurs across an air gap of up to 25 mm, allowing for contactless energy delivery. The module includes communication interfaces (RS485, CAN) for power management and monitoring, enabling feedback control and status reporting.
