A winding former 20 is disclosed for forming a coil 22 for use as a distributed winding in a rotating electrical machine. The winding former is arranged to be inserted into slots 44 in the electrical machine together with the coil. This may facilitate insertion of the coil and help to achieve a higher slot fill. Once inserted, the former itself ay act as an insulating barrier between the coil and the slots. The winding former and coil are arranged for axial insertion into slots in the stator 40 of the machine., the coil being wound on the former in planar form and the end 26 then being bent up supported by the lugs 36,38 so that the assembly can be inserted in the core slots When fully inserted the end turns 26 an be shaped as required and may be realigned in an axial direction out of the slots. Single, double or partially lapped windings may be formed, coils being inserted one at a time. |
