Each substack includes in the circumferential direction lamination stack parts whose number corresponds to the number of poles of the machine. Each substack further includes a ferrite magnet arranged between its lamination stack parts, and the ferromagnetic rotor shaft. The lamination stack parts and the support disks are held together in a frictionally connected and tight fitting manner by means of axial bolts.
