Abstract
Official abstract text for this publication.
A motor rotor includes an iron core and permanent magnets provided inside the iron core. The iron core is provided with sets of mounting grooves on the iron core in the peripheral direction of the iron core, each set of mounting grooves having two or more mounting grooves provided intermittently in the radial direction of the iron core. There are sets of permanent magnets, the individual permanent magnet of each set of permanent magnets correspondingly being embedded into the individual mounting grooves of each set of mounting grooves; there is an island region between the outermost layer of mounting grooves and the periphery of the iron core, and an enhancing hole is provided in the island region, an enhancing rod being provided in the enhancing hole. A motor includes a motor stator and the motor rotor, with the motor rotor provided inside the motor stator.
