ENCLOSED-VENTILATED, ELECTRICALLY EXCITED SYNCHRONOUS MACHINE

摘要

The invention relates to an enclosed-ventilated, electrically excited synchronous machine (1) comprising a rotor (3), which is non-rotatably positioned on a shaft (7), said rotor (3) having a rotor winding (5) with individual exciter coils (15), each coil being arranged around a pole body (13). A coil winding head (16) is formed on each of the end faces of the pole body (13) and a protective element (11) is provided on each coil winding head (13), which element protects the coil winding head (16) against abrasion.
