ABSTRACT:
A cup-shaped winding for use in the rotor or stator of a motor such as a coreless motor or slotless motor makes use of leakage flux as well as magnetic flux in the main direction. The cup-shaped winding consists of wire bands which are lap wound such that they are successively shifted a given angle from one another about the rotating shaft of a core. The winding is shaped into a cylinder or cone. The portion of each wire band which is on the bottom of the cylinder or cone does not surround the rotating shaft and forms two sides that meet at a vertex lying on the periphery of the rotating shaft. The portion of each wire band which is on the curved surface of the cylinder or cone are inclined away from the rotating shaft.
