    • 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.
    • 磁通屏障式同步磁阻电机的转子包括:旋转轴; 形成为多个钢板的转子铁心彼此层叠,所述钢板具有用于插入旋转轴的轴孔,在圆周方向上彼此间隔开的多个磁通屏障组,并且具有多个磁通屏障 在径向方向上彼此间隔开,并且在相邻的两个磁通屏障组之间穿透形成耦合孔; 以及插入所述联接孔中并固定所述钢板的联接构件。 因此,电动机的制造成本和整体重量减少,并且制造工艺在缩短制造时间的情况下变得容易。 此外,获得大的耦合强度并且不发生磁饱和,从而防止电动机的功能劣化。
