MAGNET EMBEDDED TYPE ROTOR AND MANUFACTURING METHOD OF THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a magnet embedded type rotor capable of suppressing reduction in torque of a motor caused by assembling a cover for splash prevention.SOLUTION: A magnet embedded type rotor 4 includes: a cylindrical rotor core 40; each permanent magnet 50 embedded in the rotor core 40; and a cylindrical cover 60 disposed at an outer circumference of the rotor core 40. To the rotor core 40, the cover 60 is integrally fastened while dust is compressed and molded.SELECTED DRAWING: Figure 3
