Electric motor and air conditioner

An electric motor comprising:

• an annular stator;
• and
• a consequent-pole-type rotor comprising:
• an annular rotor core disposed on an inner side of the annular stator, and
• a plurality of permanent magnets disposed inside the annular rotor core and arrayed in a circumferential direction of the annular rotor core, wherein
• the annular rotor core has:
• at least one first slit provided inside the annular rotor core, the at least one first slit being disposed on an outer side of each of the permanent magnets in a radial direction of the annular rotor core, and
• at least one second slit provided on an outer circumferential surface of the annular rotor core, the at least one second slit being disposed between closest neighboring permanent magnets among the permanent magnets, and wherein
• the at least one first slit including no opening section on the outer circumferential surface of the rotor core,
• the at least one second slit being opened to the outer circumferential surface of the rotor core,
• flux barrier sections are provided at opposite end portions of the permanent magnet, and
• an end portion of each of the flux barrier sections is parallel to the second slit adjacent to the end portion;
• and wherein
• a width of the at least one second slit in a direction orthogonal to the radial direction of the rotor core is larger than a width of the at least one first slit in the direction orthogonal to the radial direction.
