  • Patent number: 4351102
    Abstract: The first, second and third winding for the stator of a three phase AC machine having n grooves per pole and phase are wound either sequentially or simultaneously. When wound sequentially, the first, second and third winding start at, respectively, a first, second and third groove and end at a first, second and third end groove. The starting grooves are adjacent grooves, that is spaced from each other by a number of grooves equal to n. The same is true for the end grooves. The wires are then interconnected such that the winding start and the winding end of the second winding are electrically interchanged. The winding process takes place in one direction only. When all windings are wound simultaneously, the winding process takes place in a first direction and, upon reaching the end grooves, the winding direction is reversed without creating a winding end at the end grooves. The winding ends are created when the winding in the opposite direction is completed.

  • Patent number: 4307311
    Abstract: A three-phase stator winding of an alternator is divided into six partial windings. Each partial winding, regardless of electrical phase, is wound starting at the slot immediately adjacent to the slot wherein the last previously wound winding was started and in the same winding direction. The first partial windings for the subsequent phases are also inserted in the slots in the same direction as the first partial winding for the first phase, so that connecting arcs are formed on the same side of the stator as was the case for the first phase. The second partial windings for each phase are placed so that the connecting arcs form on the side of the stator opposite to that on which the first connecting arcs were formed. The winding starts and winding ends of each of the partial windings associated with a given phase are connected so that the partial windings are connected either in series or in parallel. The so-formed series or parallel circuits are then connected to form either a Y or a .DELTA. configuration.
