Parallel paths in wave winding formula
Did you know?
WebFor a four pole generator you will find 4 parallel branches of windings. From brush to brush you can consider each winding as a dc source and they are all in series so you will find Brush (lamella)- winding- lammela - winding -lammela - winding - brusch (lamella). This in two paths for a 2 pole machine and 4 paths for a 4 pole machine and so on. Webbelonging to the same winding path need to be present in each slot/pole/phase, irrespective of the layer. If multiple parallel paths are required, the impedance for each parallel path must be the same to avoid current unbalance . and additional copper losses. This means the hairpin winding . should be transposed, i.e. each winding path needs to be
