Asynchronous starting and synchronous reluctance electric motor rotor, electric motor and compressor

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 interval along a d-axis of the rotor core;
• and
• a second magnetic barrier structure, comprising two communicating magnetic barrier slots arranged at interval along the d-axis, the two communicating magnetic barrier slots being respectively located on two 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 q-axis, and
• a central through hole, through which a rotating shaft runs;
• when some or all of the first magnetic barrier portions are second arc-shaped slots, the second arc-shaped slots are arranged to evade the central through hole;
• and the second arc-shaped slots protrude toward a side away from the central through hole.
