MOTOR ROTOR AND MOTOR HAVING SAME

摘要

Disclosed is a motor rotor, comprising an iron core (10) and permanent magnets (20) provided inside the iron core (10). A plurality of sets of mounting slots (30) are circumferentially distributed in the iron core (10). Each set of mounting slots (30) comprises two or more layers of mounting slots (30) provided at intervals in radial direction of the iron core (10). There are a plurality of sets of permanent magnets (20), and the permanent magnets (20) of each set of permanent magnets (20) are correspondingly embedded into the mounting slots (30) of each set of mounting slots; one island-shaped region (12) is formed between each outermost layer of mounting slot (30) and the periphery of the iron core (10), and one reinforcing hole (13) is provided in each island-shaped region (12); one reinforcing rod (60) is provided in each reinforcing hole (13). Also disclosed is a motor, comprising a motor stator (50) and the motor rotor mentioned above. The motor rotor is provided at the inner side of the motor stator (50). The motor rotor enhances the structural strength of the whole rotor and improves the performance of the motor.
