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). The iron core (10) is provided with sets of mounting grooves (30) in the peripheral direction of the iron core, each set of mounting grooves (30) comprising two or more mounting grooves (30) provided intermittently in the radial direction of the iron core (10). There are sets of permanent magnets (20), the individual permanent magnets (20) of each set of permanent magnets (20) correspondingly being embedded into the individual mounting grooves (30) of each set of mounting grooves. Disclosed is a motor comprising the above-mentioned motor rotor. The motor rotor increases the magnetic reluctance torque of the motor rotor and thus increases the output torque of the motor and the efficiency of the motor.
