Claims

[Scope of utility model registration request]

(1) A rotor with permanent magnets formed by sintering a hard magnetic material such as ferrite or rare earth and glued to the rotor shaft to form magnetic poles, and a rotor that faces this rotor through a gap. In a permanent magnet type rotating electrical machine having a stator winding in plural grooves of a cylindrical stator core and a stator, the magnet mounting surface of the rotor shaft and the adhesive surface of the permanent magnet are flat. A permanent magnet rotating electric machine characterized in that the permanent magnets are mounted and arranged in a skewed manner with respect to the axial direction.

(2) The permanent magnet rotating electrical machine according to claim 1, wherein the axial end face of the permanent magnet is parallel to the plane perpendicular to the axis.
