Abstract
A rotor of a flux barrier type synchronous reluctance motor comprises: a rotation shaft; a rotor core formed as a plurality of steel plates are laminated to one another, the steel plate having a shaft hole for inserting the rotation shaft, a plurality of flux barrier groups spaced from one another in a circumferential direction and having a plurality of flux barriers spaced from one another in a radial direction, and a coupling hole penetratingly-formed between the adjacent two flux barrier groups; and a coupling member inserted into the coupling hole and fixing the steel plate. Accordingly, a fabrication cost and an entire weight of the motor are decreased, and a fabrication process is facilitated with a shortened fabrication time. Also, a large coupling intensity is obtained and a magnetic saturation does not occur, thereby preventing a function degradation of the motor.
