1. An electrical machine arrangement for driving an electrically drivable motor vehicle, comprising:
an electrical axial flow machine having a stator and a rotor, wherein the rotor is supported for rotation inside the electrical machine arrangement by at least one bearing point, the stator has at least a first stator half and a second stator half, axially spaced apart from the rotor on respective different axial sides by an air gap, and at least one spacer element axially orientating at least two assemblies relative to one another, the assemblies including: the first stator half, the second stator half, and the rotor, wherein the first stator half is coupled to a rotor shaft by a first bearing point, and the second stator half is coupled to the rotor shaft by a second bearing point, the rotor is in non-rotatable contact with the rotor shaft, and the axial orientation of at least one of the first stator half or the second stator half to the rotor is fixed by the at least one spacer element, and the first bearing point and the second bearing point support the rotor both axially and radially via the rotor shaft on the first stator half and the second stator half.
