| 摘要 |
The invention relates to an electric machine (1), which has a rotor (2), which has a front rotor end face (3), a rear rotor end face (4), and a rotor axis (20). A first air-cooling channel (5) extends within the rotor (2) in the axial direction of the rotor axis (20) from the front to the rear rotor end face (3, 4). A swirling web (7, 8) protrudes into the air-cooling channel (5, 6) as radial projections. The swirling web (7, 8) extends in the axial direction of the rotor (2). |
