Abstract

In order to achieve optimum rear cooling of the pole coils (9) in salient-pole machines, a U-shaped guiding device (12), which extends virtually up to the pole cap (5), is pushed into the gap between the pole core (4) and the pole coil (9). The coolant is ducted through the spaces (15, 16) formed thereby. In this way, high coolant speeds are achieved, which lead to increased heat transfer values and hence reduce the conductor temperatures of the pole coils. <IMAGE>
