ROTOR AND METHOD FOR MANUFACTURING ROTOR |
摘要 |
A rotor includes: conductors having a bar shape; a first end ring joined to one ends of the conductors by friction stir welding, at least a surface opposite to a surface from which the conductors extend being stirred by the friction stir welding; a second end ring joined to other ends of the conductors by friction stir welding, at least a surface opposite to a surface from which the conductors extend being stirred by the friction stir welding; and an iron core disposed between the first and the second end rings, having a cylindrical shape, and including a plurality of insertion holes through which the respective conductors are insertable in a central axis direction of the iron core. |
