Title:
ROTOR AND MOTOR EQUIPPED WITH ROTOR
Document Type and Number:
WIPO Patent Application WO/2020/050280
Kind Code:
A1
Abstract:
An embodiment of the present invention provides a rotor and a motor equipped with the rotor, wherein a plurality of flux barrier groups and slot groups are provided with intervals therebetween in the circumferential direction of a rotor core, thereby enabling a number of flux barrier groups and slot groups to be arranged flexibly so as to satisfy a requirement for the number of poles for different products. Furthermore, by flexibly adjusting the quantity ratio of the flux barrier groups and slot groups and/or the quantitative relationship between the flux barriers in the flux barrier groups and the slots in the slot groups, a requirement for the motor efficiency and the starting capacity can be satisfied for different products. Furthermore, a machining tool for this rotor is only required for machining the structure of the flux barriers and the slots; therefore, the manufacturing cost can be reduced.
