US Patent 10951080 Windings for an electric machine

There are disclosed winding configurations for electric machines that employ printed circuit board (PCB) type end winding connections to enable an automatic and faster assembly of the electric machines. The winding configurations provide a compact PCB-type end winding arrangement with an optimal fewer number of turns/bars in the slots of the board to complete the loop of winding connections. The winding configurations have application in three phase or multiple phase inner rotor or outer rotor electric machine topologies.
