Claims

[Scope of utility model registration request]

In a wound rotor in which a rotor winding circuit is configured by connecting an upper coil and a lower coil housed in a rotor core groove with a connecting conductor at both ends of the rotor core, the outer side of the rotor core is A rectangular spacer is provided between the upper coil and the lower coil at the end so as to maintain a distance in the circumferential direction, and a shaft is installed between the upper coil and the lower coil so as to allow ventilation from the coil end toward the core. A wound rotor characterized by a plurality of rotors arranged diagonally around the center.
