い問題が生じていた。In recent years, the capacity of water turbine generators has been increasing even further, and as a result, the core length of the magnetic pole core (6) has become longer and longer, and the length of the spider shim (1) relative to the axial direction of the ventilation duct (4) has increased. The number of installations has increased. The spider rim (1) forms a yoke that serves as a magnetic path between adjacent magnetic pole cores (6), but since the ventilation duct (4) is a space, the magnetic flux from the magnetic pole core (6) is The cross-sectional area of the road was small in this part, and the magnetic resistance was high. Due to the ventilation ducts (4) at many locations, the magnetic flux value decreases, causing a problem that the required value cannot be obtained.
