Abstract
A synchronous reluctance motor comprises a stator and a rotor, the rotor comprising: 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 spacing from each other; and a second core having a receiving hole larger than the shaft hole at a center thereof, and stacked at one side of the first core in an axial line direction. A length of the rotor protruding from a supporting portion can be decreased without reducing a stacked thickness thereof, and a vibration occurrence in a horizontal direction with respect to the rotation shaft can be reduced, thereby enhancing a reliability of the synchronous reluctance motor.
