Segmented Direct Drive Stator Layout for Lower Coil Heating

The patent divides the stator assembly into multiple independent stator units, each with its own coils and magnetic conductors. This segmentation allows each unit to generate electromagnetic thrust independently, reducing the need for excessive coil material in a single concentrated arrangement while maintaining overall thrust capability through distributed generation.

The patent transitions from a traditional concentrated coil arrangement to a distributed spatial arrangement where multiple stator units are positioned at different locations around the rotor. This dimensional redistribution of coil placement optimizes the magnetic field distribution and reduces material consumption while maintaining thrust effectiveness.

By segmenting the stator into multiple independent units with spaced coil groups, the patent distributes the electromagnetic work across multiple locations. This reduces current density and resistive heating in any single coil group, thereby reducing overall energy loss and heating quantity while maintaining the required thrust force through cumulative effect of all units.

The patent converts the potential harm of concentrated coil heating into a benefit by distributing coils across multiple stator units. The spacing between coil groups allows heat dissipation, and the distributed arrangement ensures that no single location experiences excessive heating, thus converting the constraint of heat management into an opportunity for more efficient energy utilization.
