Abstract

The invention comprises an electrical machine with a stator ( 10 ) formed of plates, said stator ( 10 ) having an outer surface ( 11 ) and a first and second end ( 12 ) in the axial direction ( 2 ) and said stator being supported on the frame ( 1 ) of the electrical machine. The stator ( 10 ) is supported by necks of material ( 40 a - d ) on the outer surface ( 11 ) at both ends of the stator. The number of necks ( 40 a - d ) at both ends of the stator is even. The stator ( 10 ) has a vertical symmetry axis ( 7 ) perpendicular to the axial direction ( 2 ) and a horizontal symmetry axis ( 8 ) perpendicular to the axial direction ( 2 ), and the necks ( 21 a - f , 31 a - d , 40 a - d ) are located symmetrically in relation to at least one of the symmetry axes ( 7, 8 ).
