1Volume of moving object
If windings are made of thin metal plates, then the device size is reduced, but the induced electromotive force becomes small
Solution Approach 1:
The coil structure is divided into multiple separate metal plate layers (first metal plate, second metal plate, third metal plate, etc.), each contributing to the overall winding. This segmentation allows for optimized current distribution and increased effective winding area, thereby enhancing the induced electromotive force while maintaining compact dimensions.
Solution Approach 2:
The patent transitions from a single-plane winding to a multi-layer three-dimensional structure. By stacking metal plates in multiple layers with alternating connection patterns, the effective winding area increases in the vertical dimension, significantly boosting the induced electromotive force without proportionally increasing the device footprint.
