Abstract (en)

[origin: WO2012059258A1] The invention relates to an electric synchronous machine (1), which comprises a rotor (3) having a plurality of poles (7). The pole width corresponds to an angle of 360° divided by the plurality of poles (7). Each pole (7) comprises a first magnet (11) and a second magnet (13) having a common magnet width (15). The magnet width (15) corresponds here to an angle that is formed between a first secant (16) and a second secant (17). The first secant (16) runs through the midpoint (19) of the rotor (3) and through a point (23) of the first magnet (11) lying closest to the rotor edge (21). The second secant (17) runs through the midpoint (19) of the rotor (3) and through a point (25) of the second magnet (13) lying closest to the rotor edge (21). The magnet width (15) amounts here to less than 75% of the pole width (9).
