TWO-LAYER MAGNET-EMBEDDED ROTOR, TWO-LAYER MAGNET-EMBEDDED ROTARY ELECTRIC MACHINE, AND METHOD FOR MANUFACTURING TWO-LAYER MAGNET-EMBEDDED ROTOR

WIPO Patent Application WO/2024/095452

A1

According to embodiments, a two-layer magnet-embedded rotor (100) comprises: a rotor shaft (110); a rotor core (120) that includes first and second outer side accommodation holes (121, 122) and first and second inner side accommodation holes (124, 125); first and second outer side magnets (131, 132); and first and second inner side magnets (133, 134). The accommodation holes (121, 122) that are to the outer side in the radial direction are not in communication with the outer side of the outer circumference of the rotor core (120). The first inner side accommodation hole (124) and the second inner side accommodation hole (125) are in communication with the outer side of the outer circumference. The value of the inside open angle Θb1 at which radial-direction outer side walls (124a) and (125a) of the inner side accommodation holes open toward the outer side in the radial direction is equal to or higher than a prescribed value and is equal to or lower than the value of the outside open angle Θa at which radial-direction outer side walls (121a, 122a) of the outer side accommodation holes open toward the outer side in the radial direction.
