In prior art multi-phase electric machines in which conductor parts are interlace to form conductor lanes for various phases, the connection points are on the winding end, thus permitting only a very limited local possibility for welding of the conductor ends. In addition, the manufacturing cost is increased with an odd number of phases, since the design is asymmetrical and a number of different formers necessary is relatively high. The invention calls for prefabricated conductor parts (17) to be welded or soldered in the zones which will subsequently be located in the soft magnetic body. Divided bars with a high conductor cross-sectional area are connected before the insertion of soft magnetic segments, connection zones which are large relative to the conductor cross-sectional area are realized, and problems with the insulation are avoided. In three-phase machines, the conductor lanes are interlaced with each other, all conductor lanes being identical in design and the same pattern is repeated every four pole pitches. This connection technique and conductor progression permits the inexpensive manufacture of reliable electric motors and generators as well as uniform space utilization in three-phase equipment.
