  • Patent number: 11929641
    Abstract: A segment core and an axial flux motor. The segment core is formed by covering an SMC core (100, 100?) over an outer peripheral surface of a laminated core (200, 200?). An outer surface of the segment core, which can not be processed easily, is shaped by processing the easily shapeable SMC core (100, 100?). The entire structure of the laminated core (200, 200?) is relatively simple, and thus a mold for processing the laminated core (200, 200?) requires simpler specifications. Moreover, the mold can be used to perform processing easily, thereby reducing difficulties of processing the segment core. The segment core has better electromagnetic performance than a segment core solely using an SMC material, and has a higher core utilization rate than a segment core solely using a laminated core (200, 200?).
