Abstract: An electric machine including a stator and a frame, the stator is supported with support necks on the frame in at least two axially spaced support locations. The support locations include a first group of support necks and a second group of support necks. The support necks in the first group are positioned in connection with a vertical centre plane. The second group includes two side support necks positioned opposite to each other at an angular distance above or below a horizontal centre plane. The angular distance is defined by a first angle which is determined in degrees by the formula α1=(90/P)±(⅕)*(90/P), where P is the number of poles of the electric machine and P>2.
