The present disclosure provides a direct starting synchronous reluctance motor rotor, and a motor. The direct starting synchronous reluctance motor rotor comprises: a rotor core provided with a plurality of slit grooves, two filling grooves are respectively disposed at two ends of each of the slit grooves to form a magnetic barrier layer, a first end of the filling groove being disposed adjacent to the slit groove, a second end of the filling groove being disposed to be extended outwards an outside of the rotor core, a beveled edge is disposed on the second end of at least one of the filling grooves away from a d-axis of the rotor core, so that a d-axis flux of the rotor core will not suddenly change when entering a stator along a channel formed at the beveled edge. With this arrangement, a reluctance torque ripple of the motor can be reduced, thereby reducing generated vibration noise, increasing a d-axis inductance and a flux difference between the d-axis and a q-axis, generating a greater reluctance torque, increasing an output torque of the motor with the rotor, and improving a motor efficiency.
