| 摘要 |
The invention relates to an electric drive (1) for an aircraft, especially for a helicopter (20) comprising at least one rotor (23) that is directly driven by a dynamoelectric machine (2). The dynamoelectric machine (2) is embodied in a duplex arrangement, a rotor (6) arranged in an air gap (12) comprising permanent magnets (13) on a carrier device (14), and the stators (4, 5) of the dynamoelectric machine (2) and/or the rotor (6) comprising coolant. A planetary gear (3) is especially provided between the driven rotor and the dynamoelectric machine (2), preferably in the axial extension of the dynamoelectric machine (2).
