EMBEDDED MAGNET MOTOR AND ROTOR OF EMBEDDED MAGNET MOTOR

An embedded magnet motor (100, 200) includes a stator core (10), a plurality of permanent magnets (21) each having a rectangular cross section, and a rotor core (20, 220). The stator core (10) and the rotor core (20, 220) define a first air gap (31) being positioned at an intermediate portion (20c)...

Zusammenfassung:An embedded magnet motor (100, 200) includes a stator core (10), a plurality of permanent magnets (21) each having a rectangular cross section, and a rotor core (20, 220). The stator core (10) and the rotor core (20, 220) define a first air gap (31) being positioned at an intermediate portion (20c) of the rotor core (20, 220), a second air gap (32) being positioned at a first portion (20a, 220a) corresponding to a first axis of the rotor core (20, 220), and a third air gap (33) being positioned at a second portion (20b, 220b) corresponding to a second axis of the rotor core (20). Because a diameter of the intermediate portion (20c) being positioned between the first portion (20a, 220a) and the second portion (20b, 220b) of the rotor core (20) is set smaller than a diameter (R1) of the first portion (20a, 220a) and than a diameter (R2) of the second portion (20b, 220b), the first air gap (31) is set greater than the second air gap (32) and than the third air gap (33)
