The invention relates to an electric machine construction and a method for the same. The machine comprises a stator space (9) defined by a shell (8) and end portions (6) at both ends of the shell (8). Stator means and rotor means of the electric machine are disposed within said stator space. Cooling medium is arranged to be conducted into the stator space (9) defined by said shell and said end portions through at least one opening (14, 34) in said shell (8). The machine further comprises means (13, 20) for providing a suction for conducting said cooling medium by means of the suction into said stator space (9).
