FIELD: electrical engineering.
SUBSTANCE: nonsalient pole rotor of synchronous electric machine contains a shaft with flux core having channels for excitation winding, exiting coils laid in channels of the flux core, rings aligning with axial ventilation channels, retaining rings and banding insulation. In pursuance of the present invention retaining rings and banding insulation are made with tangential-oriented radial slots located along length of retaining rings located in several rows preferably opposite gaps between end parts of exciting coils.
EFFECT: improved cooling of front parts of excitation coils located in channels of the core of nonsalient pole rotor of synchronous electric machine.
