The electric machine comprises a rotor, a stator and a support structure. The stator comprises a stator core and a stator frame. The stator frame has axial (X-X) ends and longitudinal sides. The rotor is supported with bearings on the support structure. An end support structure of cast iron is provided at each end of the stator frame. The end support structure is formed of a longitudinal middle portion and two upwards directed end portions. The end support structure extends in a traverse direction between outer edges of the axial (X-X) end of the stator frame. The end support structure is attached with compression joints to the support structure and to the axial (X-X) end of the stator frame.
