Claims

[Scope of utility model registration request]

A plurality of axial slots are provided on the outer periphery of the cylindrical rotor core, which is divided in the axial direction by radial ducts, and rotor windings are wound in these slots, so that the rotor core is axially ventilated. The coil end portion of the rotor winding δ is supported on the outer periphery of the rotor holding plate fitted to the rotary shaft, and a ventilation device is used to connect the outer side of the rotor core and the rotor winding. In a rotating electric machine equipped with a rotor that performs axial ventilation to the outside of the wire and the same axial ventilation as the outward axial ventilation of the rotor winding through a radial tact from the rotation shaft ventilation groove. , rotate the rotor press plate on the downstream side of the axial ventilation in the axial direction 2. The first rotor holding plate, which is divided to open the inner circumferential middle of the downstream coil end and supports the tip end of the coil end, seals the part fitted to the rotating shaft to prevent axial ventilation. The part of the 72nd rotor holding plate that supports the coil end core side that fits onto the rotating shaft extends the axial ventilation groove of the rotating shaft and communicates with the intermediate open part of the downstream coil end. A rotating electrical machine characterized by radial ventilation inside the side coil end.
