Abstract (en)
[origin: WO2017129407A1] According to the invention, in order to construct a rotor (100) of an electrical machine (101) in a simple and cost-effective manner and, in the process, achieve low skin effect losses and a high tilting moment using low tooth tip distribution, the rotor (100) is to be constructed with a substantially cylindrical laminated core (102) comprising axially (A) layered metal sheets, wherein substantially axially (A) extending grooves (103) are formed in the laminated core (102) along a circumferential surface (104) of the laminated core (102), of which grooves some are configured to be open to the circumferential surface (104) via a respective scattering slit (108) extending radially (R) outwards from the groove (103) to said circumferential surface (104), and wherein the electrically and magnetically non-conductive closure elements (110) are accommodated in the scattering slits (108), extending in the axial direction (A) thereof and at least partially interlockingly locking the grooves (103) to the circumferential surface (104). The invention also relates to an electrical machine (101) comprising a rotor (100) of this type and a method for producing a rotor (100) of this type.
