Method for assembling the rotor (R) of an electric machine including a rotor (R) solid with a shaft (4) having a longitudinal axis (x-x) and made by more identical permanent magnets (2) forming a rotor ring. Each of the said permanent magnets (2) is a parallelepiped body. The method comprises the following steps: providing a first annular flange (9); forming a plurality of fixed linear guides onto a side of the said first annular flange (9), the said guides being angularly regularly spaced and orthogonal to the flange on which they are formed; inserting the magnets (2) in said guides and sliding the magnets towards the said first flange (9); positioning of a second annular flange (90) on said guides; locking of the said second flange (90) to the said guides, so that the said magnets (2) are clamped, inside said guides, by the first and the second flange (9, 90). The said guides are formed in the following way: inserting a rod (13) through each of a plurality of passing holes (91) provided in said first flange (9) and locking the rods (13) orthogonally to the said first flange (9); fitting, on each of said rods (13), a body (12) having a central portion with a passing hole (121) and two side arms (122) on opposite sides with respect to the central part, said arms (122) being orthogonal to said central part of the body (12), the latter being positioned with its central portion bearing on the flange (9) and with its arms (122) turned upwardly; fitting a tubular spacer (11) on each rod (13); fitting, on each rod (13), a further body (12) with a central portion having a passing hole (121) and two side orthogonal arms (122) turned downwardly. |
