Title:
アキシャルギャップ型回転電機の製造方法
Document Type and Number:
Japanese Patent JP5889765
Kind Code:
B2
Abstract:
An axial gap dynamoelectric machine is provided with a stator core in which continuously wound coils (10a, 10d, 10g, 10j) including a plurality of coils formed of continuously wound insulation-coated conductor wire are disposed in a circumferential direction with the continuously wound coils of the three phases overlapped. With the respective coils being disposed in a radiating shape, the continuously wound coils are configured so that on the inner diameter side of the coils, the insulation-coated conductor wires are continuously wound to adjacent coils via crossover wires (15U2, 15U3, 15U4, 15U5), and the coils are bent in the vertical direction and the continuously wound coils of each phase are made to overlap with each other so that the length (2×L3+L2) of the crossover wires can be adjusted regardless of the core layer thickness (L1) of the stator core. This configuration makes it possible to reduce copper loss, achieve a price reduction and improve durability, insulation properties and cooling performance of the axial gap dynamoelectric machine.
