Patent ID: 11824409

Abstract:
The present disclosure provides a direct starting synchronous reluctance motor rotor, a motor and a rotor manufacturing method. The direct starting synchronous reluctance motor rotor comprises: a rotor core provided with a plurality of slit grooves, two ends of each of the slit grooves being provided with a filling groove respectively 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 extended towards an outside of the rotor core, and an outer peripheral surface of the rotor core being provided with a notch communicated with the second end of the filling groove. By disposing notches and bevels at the end of the filling grooves, a reluctance torque of the motor can be increased, and then torque ripples generated by rotor and stator slots can be weakened mutually, thereby achieving the purpose of reducing the torque ripple of the motor and vibration noise of the motor, while improving an efficiency of the motor with the rotor and a starting capability of the motor.
