ROTOR, ROTOR CORE, AND MANUFACTURING METHOD OF ROTOR

摘要

PROBLEM TO BE SOLVED: To provide a rotor the strength of which against centrifugal force is enhanced while minimizing leakage of magnetic flux, and to provide a rotor core and a manufacturing method of rotor.

SOLUTION: A rotor 10 comprises: a rotor core 32 in which a slit lamination hole 22 for embedding a magnet 20 is formed by laminating a plurality of core sheets 18 having a slit 16, and the core sheet 18 is provided with one end bridge 26 and the other end bridge 30; and the magnet 20 embedded in the slit lamination hole 22 of the rotor core 32. A split bridge 34 for splitting the slit 16 into two in the longitudinal direction thereof is provided in the slit 16 of some core sheets 18 at an intermediate part of the slit 16.
