FIG. 20 is a partially enlarged cross-sectional view illustrating an interior permanent magnet motor according to an embodiment of the disclosure.
Referring to FIG. 20, an interior permanent magnet motor 500 according to an embodiment of the disclosure may include a stator 510 and a rotor 520.
The stator 510 is formed similarly to the stator 110 of the interior permanent magnet motor 100 according to the embodiment of FIG. 11.
The rotor 520 is formed similarly to the rotor 120 of the interior permanent magnet motor 100 according to the embodiment of FIG. 11. A plurality of permanent magnets 530 inserted into the rotor 520 are V-shaped like the permanent magnets 130 of the embodiment of FIG. 11.
However, the interior permanent magnet motor 500 as illustrated in FIG. 20 differs from the interior permanent magnet motor 100 of FIG. 11 in the ratio of the number of slots 515 of the stator 510 to the number of magnetic poles of the rotor 520.
The interior permanent magnet motor 500 illustrated in FIG. 20 has the ratio of the number of slots 515 of the stator 510 to the number of magnetic poles of the rotor 520 of 3:4. In detail, the stator 510 has six slots 515, and the rotor 520 has eight magnetic poles.
