Beschreibung
Zusammenfassung:	A rotor for reducing eddy current loss, includes a rotor yoke, the rotor yoke has a fixing portion, and an inner ring portion and an outer ring portion connected to the fixing portion and disposed in the same direction; and a ring-shaped magnetic steel assembly, affixed to the fixing portion and radially affixed by means of the inner ring portion and the outer ring portion. The inner ring portion and/or the outer ring portion are uniformly provided with multiple channels blocking a transmission path of an eddy current, so as to increase resistance of the eddy current and thereby reduce eddy current loss, effectively preventing heating caused by eddy current loss, as well as preventing the phenomenon of magnetic steel demagnetization from occurring and affecting service life.
