A1
Abstract:
The electrical device comprises an end shield (2) comprising a first side (201) facing towards an internal space (9) of the electrical device and a second side (202) opposite to the first side (201); a bearing (3) arranged on the end shield (2); an output shaft (4) arranged in the bearing (3) and protruding out of the second side (202) of the end shield (2); and a heat insulation layer (5) arranged on the first side (201) of the end shield (2) around the bearing (3) to prevent hot air in the internal space (9) of the electrical device from reaching the end shield (2). In this way, the temperature of the end shield (2) and thus the temperature of the bearing (3) may be lowered during the operation of the electrical device.
