Abstract

A rotor for an electric machine, having a laminated core, which is arranged on a shaft and provided with magnets. Multiple individual adjoining plates pushed onto a shaft or of partial laminated cores having multiple plates have a central borehole accommodating the shaft. At least a part of the plates or partial laminated cores are pushed onto the shaft pivoted by a predetermined pivot angle (α). Every plate or partial laminated core includes multiple coolant passages arranged distributed around the center (Z) of the borehole. The angle offset of two adjacent coolant passages corresponds to the pivot angle (α).
