1. An electrical machine, comprising:
a stator defining an axis, said stator having two axial ends and including spring elements arranged on a radially outer periphery of the stator;
a rotor mounted relative to the stator for rotation about an axis of rotation and surrounded by the stator radially on the outside,
a housing shrunk onto the stator from radially outside such that the spring elements are at least partially elastically deflected radially inward so as to abut the housing with a spring force; and
end plates respectively attached to each of the two axial ends of the stator, with the spring elements being arranged on the end plates and configured as projections which extend in a direction of the axis from a flat main element of the end plates away from the stator.
