Abstract
The utility model discloses a megawatt grade external electric excitation direct driving wind driven generator, which is installed outside a cabin. A cooling wind channel is arranged at the gap position between a rotor and a stator in the generator to form a structure that generator casing radiating is taken as the primary thing and internal ventilation heat exchange is taken as the secondary thing. Due to the fact that the generator is installed outside the cabin, external air cooling resources are fully utilized, radiating energy consumption in a system is reduced, and effect of generator loss heating on internal temperature of the cabin is removed. Simultaneously, the cooling wind channel is arranged at the gap position between the rotor and the stator, cooling effect on generator winding is improved to the largest extent, and the problem that the existing megawatt grade internal electric excitation direct driving wind driven generator is large in radiating energy consumption. The generator has the advantages of being low in radiating energy consumption, good in radiating effect and good in magnetic field adjusting performance.
