An electric machine (1) for a hybrid or electric vehicle has an external rotor and a stator (2) within the rotor (3). The rotor (3) has a rotor carrier (4), rotor plates (5) and permanent magnets (6). The rotor carrier (4) has a first, radially extending carrier section (7) and a second axially extending carrier section (8). The second carrier section (8) bears the rotor plates (5) and permanent magnets (6). The stator (2) has stator plates (9) and wire windings (10) that form winding heads (11, 12) extending axially on both sides over the stator plates (9). An impeller wheel (14) is connected to the rotor carrier (4) and is between the winding heads (11) on an axial side of the stator (2), and the second carrier section (8). The electric machine provides high power in a small axial extent with optimum air cooling of the rotor and stator. |
