Abstract
A permanent magnet rotor for a motor, the permanent magnet rotor including an iron core and a permanent magnet. The iron core includes an annular ring having a central axial bore and a plurality of magnetic induction blocks protruding outward from an outer side of the annular ring. Between two adjacent magnetic induction blocks form a radial recess for mounting the permanent magnets. The magnetic induction blocks at both sides of an opening of the radial recess protrude with a hook block. The section of an outer side surface of the magnetic induction blocks is a circular-arc line and the outer side surface employs a point with a distance deviating from the center of the central axial bore as a center of circle.
