PURPOSE:To contrive the simplification of a structure, the reduction of numbers of parts and saving-energy in soldering work, and the improvement of a product in reliability by a method wherein the interpole crossover track is used as a part of a starting end and finishing end of a coil to eliminate a soldered structure. CONSTITUTION:The interpole 6a, 7a are made crossover means directly crossing over is a shape in which a coiled bottom turn of the conventional interpole crossover track is integrated included, at the starting (finishing) end 6 of the N-pole coil and the finishing (starting) end 7 of the S-pole coil. The crossover means 6a, 7a are put on the top of each other without being soldered on the S-pole coil finishing (starting) end 7 and the N-pole coil starting (finishing) end 6 and form a circuit of the interpole crossover track. Thereby the structure is simplified, the numbers of the parts are decreased, the soldering energy is saved, a fatigue strength of the crossover track is increased and the reliability of the product is improved.
