An asynchronous starting and synchronous reluctance electric motor rotor, comprising a rotor core, the rotor core comprising: a first magnetic barrier structure, comprising multiple groups of first magnetic barrier portions arranged at an interval along a q-axis of the rotor core; and a second magnetic barrier structure, comprising two communicating magnetic barrier slots arranged at an interval along the q-axis, the two communicating magnetic barrier slots being respectively located on two opposite, relative to the q-axis, sides of the first magnetic barrier structure, the communicating magnetic barrier slots being arc-shaped slots extending circumferentially along the rotor core, and slot walls of two ends of the arc-shaped slots being arranged parallel to a d-axis; wherein some of the first magnetic barrier portions are linear slots and some of the first magnetic barrier portions are slots each comprising an arc, the linear slots being located between the communicating magnetic barrier slots and the slots each comprising an arc; the first magnetic barrier structure further comprises multiple supplementary slots, wherein each of the multiple supplementary slots is located between a d-axis end of a first magnetic barrier portion of the first magnetic barrier portions and a radially outer edge of the rotor core, and each supplementary slot extends in a direction parallel to the d-axis; the second magnetic barrier structure further comprises four independent magnetic barrier slots, the four independent magnetic barrier slots being pairwise located on two sides of the q-axis, wherein each two independent magnetic barrier slots form a group and are arranged at an interval, wherein the q-axis position of each the independent magnetic barrier slots is located between the q-axis position of a linear slot and a slot comprising an arc, the supplementary slots and the second magnetic barrier structure are filled with a material that is electrically conductive but not magnetically conductive; wherein there are cast-aluminum end rings at two ends of the rotor core, and by the cast-aluminum end rings, all of the communicating magnetic barrier slots, the supplementary slots and the independent magnetic barrier slots are communicated to each other to form a squirrel cage; wherein during the operation of the asynchronous starting and synchronous reluctance electric motor rotor, magnetic flux lines enter the rotor core from both q-axis sides of the independent magnetic barrier slots, and then flow in channels between the linear slots and the slots each comprising an arc. a first magnetic barrier structure, comprising multiple groups of first magnetic barrier portions arranged at an interval along a q-axis of the rotor core;
