| 摘要 |
The invention relates to an electric machine comprising a stator (16) and a rotor (20), differently polarized excitation poles (24, 25), especially claw poles, that are adjacent on the periphery of the rotor (20) facing the stator (16), the excitation poles (24, 25) having pole flanges (65) and the pole flanges (65) of differently excitable, adjacent excitation poles (24, 25) facing each other. The pole flanges (65) of the excitation poles (24, 25) have a flange depth (TEP) which points at least substantially radially inwards in their direction of extension (XEP) and for every position in the direction of extension (XEP). Pole gaps (63) are defined between the excitation poles (24, 25) and at least one permanent magnet (70) is arranged in at least one pole gap (63) and counteracts a leakage flux between its adjacent excitation poles (24, 25) when operated. The permanent magnet (70) has flanges (100) and one of the flanges (100) faces a pole flange (65)of an excitation pole (24, 25) and the other flange (100) faces a pole flange (65) of another excitation pole (24, 25), the two excitation poles (24, 25) being adjacent and being differently polarized. The flanges (100) of the permanent magnet (70) have a flange depth (TPM) which points at least substantially radially inwards in their direction of extension (XEP) and for every position in the direction of extension (XEP). The invention is characterized in that the two flanges (100) of the permanent magnet (70) facing differently polarizable excitation poles (24, 25) at least in some sections thereof have flange depths (TPM) that are substantially adapted to the flange depths (TEP) of the excitation poles (24, 25). |
