Rotating Electric Machine Parallel Winding Segmentation

The patent divides the coil into two separate rows (first row and second row) based on turns count, with each row containing a specific number of turns. This segmentation allows the coil to be inserted in a divided manner, reducing the quantity of copper wires that need to be handled at once while maintaining the total wire count. The segmentation principle directly addresses the contradiction by breaking down the single complex coil insertion into two simpler row-based insertions.

Instead of series-connecting the two rows as conventionally done, the patent inverts the connection approach by parallel-connecting the first row coil and the second row coil. This inversion of the connection method (from series to parallel) reduces the number of end-to-end connections required, as the parallel connection allows both rows to be connected to the same terminals without requiring intermediate series connections between rows.

The distributed winding is segmented into two distinct rows (first row and second row) with specific turn allocations. This segmentation provides manufacturing flexibility by allowing each row to be independently prepared and inserted, while the parallel connection approach ensures that the number of connection sites does not multiply, thus resolving the contradiction between manufacturing ease and device complexity.

The patent merges the connection points of the two rows by parallel-connecting them to the same terminals. Instead of creating separate series connection paths that would increase the number of connection sites, the parallel connection merges the electrical paths, allowing both rows to share common terminals and thereby reducing the total number of connection sites required.
