Abstract:
A magnet plate used for a rotor core of a motor, includes a magnetic pole portion being set between an outer peripheral edge of a body portion and a magnet slot and having a radial width being smaller than a radial sectional width of the permanent magnet, and a higher hardness portion being formed into a hook shape along an end corner of the magnet slot and have a smaller width than the radial sectional width of the permanent magnet.
