効率を低下させる原因として問題点とされている。This will be specifically described with reference to FIG. 1, for example, as in the conventional electric motor or generator, the slot 3 on the outer peripheral surface side.
When a motor or a generator is configured only by combining the armature winding wound around the tooth part of the field and the field 7, and when the number of phases is three, the armature winding has slots 3 of the same phase. It will be wound between the slots 3 ', and the length of the line connecting the slots will be the length of the section ac.
Since it becomes significantly longer than the length of the ab section, this point is a problem as a cause of lowering the efficiency.
