Abstract: An embodiment of the present invention provides a rotor and a motor having the rotor. By providing a plurality of flux barrier groups and slot groups at intervals in a circumferential direction of the rotor iron core, it is possible to flexibly arrange the numbers of the flux barrier groups and the slot groups so as to meet the requirements for the number of poles of different products. In addition, by flexibly adjusting the quantity ratio between the flux barrier groups and the slot groups and/or the quantity relationship between the flux barriers in the flux barrier group and the slots in the slot group, it is possible to meet the requirements for motor efficiency and starting capacity of different products. Further, since the processing jig of the rotor only requires processing of the structures of the flux barriers and the slots, the manufacturing cost can be reduced.
