Abstract:
1. A synchronous reluctance motor, comprising: a stator; and a rotor, wherein the rotor comprises: a rotation shaft; a first core having a shaft hole for inserting the rotation shaft at a center thereof, and having a plurality of first flux barrier groups arranged along a circumferential direction of the shaft hole and spaced from each other; and a second core having a receiving hole larger than the shaft hole, the receiving hole and the shaft hole having substantially a same center, and stacked at one side of the first core in an axial line direction, the second core having a plurality of second flux barrier groups arranged along a circumferential direction of the shaft hole and spaced from each other, wherein each of the first flux barrier groups comprises a plurality of slots arranged towards the shaft hole from a circumference of the first core with a gap therebetween, and wherein each of the second flux barrier groups comprises a plurality of slots arranged towards the receiving hole from a circumference of the second core with a gap therebetween, and wherein at least one slot adjacent to the shaft hole among the plurality of slots in each first flux barrier group overlaps in the axial line direction the receiving hole of the second core.
