WIPO Patent Application WO/2024/083155
Kind Code:
A1
Abstract:
A motor, a compressor, and a refrigeration device. The motor comprises a rotor (100) and a stator (200). The rotor (100) comprises a rotor iron core and a plurality of permanent magnets (120) provided on the rotor iron core, and the permanent magnets (120) each contain a cerium element having a mass percentage of x%; the stator (200) comprises a stator iron core, Q stator teeth (210) are provided on the stator iron core in the inner circumferential direction, a stator winding is wound on each stator tooth (210), and the number of phases of each stator winding is m; the mass percentage x% of the cerium element meets: 3%≤x%≤10%; the number Q of the stator teeth (210) and the number m of phases of each stator winding satisfy the relationship: Q/m≤3; and the width of magnetic poles of the rotor (100) is bm, and bm satisfies the relationship: bm≥3040/(165-x).
