Motor coil substrate with overlapping flexible coils
The patent US12040671B2 describes a motor coil substrate designed to enhance the efficiency and functionality of electric motors. The substrate consists of a flexible material that is wound multiple times, specifically N times where N is 2 or greater. It features a series of coils, arranged in groups of three (U-phase, V-phase, and W-phase), which are strategically positioned to partially overlap when the substrate is wound. This configuration allows for a compact design while maintaining effective electrical performance. The substrate can include multiple layers, with additional flexible substrates extending outward, each containing coils that also overlap, thereby optimizing space and enhancing the motor's operational capabilities.
The claims further detail the structural characteristics of the coils, including their spiral wiring and the arrangement of center spaces that allow for openings penetrating through the substrate. This design is intended to ensure that when a magnet is placed within the substrate, the angle between the wiring and the motor's rotation direction is approximately 90 degrees, which is crucial for efficient motor operation. The patent also specifies the dimensions and gaps between the coils, ensuring uniformity and effective electromagnetic interaction. Overall, this innovative motor coil substrate aims to improve the performance and compactness of electric motors, making it a significant advancement in motor technology.
