COIL WINDING METHODS AND STRUCTURES FOR A SLOTLESS STATOR IN A MOTOR |
摘要 |
A method to form a field winding for a slotless stator including: forming the first coil group by spirally winding an insulated wire for each coil winding around a mandrel such that each turn of the wire is adjacent a next turn of the wire; after forming the first coil group, axially shifting along the mandrel the insulated wire from a trailing edge of each coil winding to position the wires at a leading edge of each of coil winding in the second coil group; forming the second coil group by spirally winding the insulated wire for each coil winding around a mandrel; removing the mandrel from the wound first and second coil groups; collapsing the wound coil groups to a layer web such that coil winding segments are interleaved; and wrapping the web into a cylinder to form the field winding.
