MANUFACTURING METHOD FOR ROTOR AND MANUFACTURING APPARATUS FOR ROTOR

摘要

PROBLEM TO BE SOLVED: To provide a manufacturing method for rotor which allows for application of the magnetic field of a magnetization coil to a magnet in a desired direction, while allowing positional deviation of the magnetization coil from the rotor core.SOLUTION: Magnetization coils 15A, 15B are arranged on the axial outside of the axial ends 11a, 11b so as to be coaxial with the axis L of a rotor core 11, and each magnet 14 assembled in the rotor core 11 is magnetized in the radial direction, by a magnetic field generated by electrifying the magnetization coils 15A, 15B.
