Abstract

W układzie chłodzenia czół uzwojenia maszyny elektrycznej z wirnikiem zewnętrznym lub wewnętrznym, przestrzeń pomiędzy czołem uzwojenia (1), rdzeniem magnetycznym (2), elementem nośnym (5) rdzenia magnetycznego oraz radiatorem bocznym (3) jest zalana żywicą ciepłoprzewodzącą (4). Dodatkowo powierzchnia radiatora bocznego (3) posiada rowki (7) umiejscowione od strony czół uzwojenia (1) oraz od strony tarczy wirnika (6). Rowki radiatora (3) mogą mieć kształt okręgu lub podłużne. Na wirniku (6) znajdują się łopatki (8). W tarczy wirnika (6) znajdują się łopatki oraz otwory.In the cooling system of the winding faces of an electric machine with an external or internal rotor, the space between the winding face (1), the magnetic core (2), the magnetic core bearing element (5) and the side heat sink (3) is filled with heat-conducting resin (4). Additionally, the side heat sink surface (3) has grooves (7) located on the side of the winding faces (1) and on the side of the rotor disc (6). The heat sink grooves (3) may be circular or oblong. There are blades (8) on the rotor (6). There are blades and holes in the rotor disc (6).
