Abstract
The present invention relates to a slotless winding for a rotating electric machine and a manufacturing method thereof. The slotless winding includes at least one flexible printed circuit board having at least one circuit, and one piece of flexible printed circuit board(s) is curved or a plurality of pieces of flexible printed circuit board(s) is mutually combined to form a barrel shape, thereby simplifying the procedure of manufacturing the slotless winding, improving production speed and reliability, and enabling diversified designing schemes to meet the demands of the rotating electric machine. In addition, it is not necessary for the coil winding to be cured for assembling, and assembling yield is thus enhanced.
