ABSTRACT:
The object of the invention is a method and installation means for installing an electrical machine, particularly for installing a rotor within a stator. According to the invention, two or more spacer elements (32) are fitted on the outer circumference of the rotor (6), the distance between the outermost part of these spacer elements and the rotor's central axis of rotation (7) being smaller than the inner radius of the stator (2) and greater than the outer radius of the rotor (6), and the rotor is inserted into the stator in the direction (S) of its shaft.
