Claims

[Scope of utility model registration request]

A permanent magnet rotor in which magnets are adhesively fixed to the outer periphery has a protrusion on one surface that presses the magnet toward the rotating shaft between each magnet pole, and a stepped surface perpendicular to the axis of the rotating shaft. It has a protrusion that fits into the provided hole,
A permanent magnet rotor characterized in that two reinforcing magnet pressers having a circumferential groove on the other surface are arranged with magnets sandwiched therebetween.
