An electric machine comprising a support frame (6), an outer rotor (2), a stator (4), and dampening means, the outer rotor (2) and the stator (4) being supported to the support frame (6), the dampening means being adapted for dampening vibrations of the outer rotor. The outer rotor (2) comprises an annular end plate (28), the dampening means comprises a first damper (10; 10'; '') having a first constraint element (12; 12'; 12'')and a first visco-elastic layer (14; 14'; 14'') provided on a surface of the first constraint element (12; 12'; 2''), the first constraint element (12; 12'; 12'') being connected to the annular end plate (28) through the first visco-elastic layer (14; 14'; 14''). |
