Abstract

The 3-phase generator has at least one bearing plate (14) provided with flat radial webs (36) connecting its bearing socket (16) to its periphery (37). These webs are inclined to the long axis of the generator spindle. The width of the webs across the direction of the spindle's long axis is large compared to their thickness in the direction of the spindle's long axis. The webs are shaped aerodynamically to form turbine blades that convey air through the generator. The angle of inclination (about 30 deg.) of the webs is chosen such that the max. amount of cooling air is driven through the generator when the generator is running at its average speed.
