The invention provides a self-starting synchronous reluctance motor which comprises a stator and a rotor, the rotor comprises a rotor rotating shaft, a rotor iron core and rotor conducting bars, a plurality of rotor grooves are uniformly punched in the outer edge of the rotor iron core in the circumferential direction with the rotor rotating shaft as the center, and the non-magnetic copper or aluminum conducting bars are placed in the rotor grooves. The end parts are connected through end rings to form a starting cage, a plurality of groups of 1-8 axially-through magnetic barrier layers are arranged between a rotor rotating shaft and a rotor groove, and the group number of the magnetic barrier layers is the number of poles of the motor, so that the problems that the permanent magnet of the existing self-starting permanent magnet synchronous motor has the risk of irreversible demagnetization, the permanent magnet material and the fixing cost thereof are high, and the cost is low are solved. The problems that f
