Synchronous machine with inner rotor, excited by permanent magnets

摘要: A synchronous machine including a rotor having at least two lamination substacks, between which are arranged support disks of nonmagnetic material firmly mounted on the ferromagnetic shaft. Each substack includes in circumferential direction stack parts whose number corresponds to poles machine. further ferrite magnet its parts, and The held together frictionally connected tight fitting manner by means axial bolts.
