Abstract
A permanent magnet rotor has a rotor core positioned about a rotation shaft. The permanent magnet rotor also has permanent magnet embedment slots located at equally spaced positions from the rotation shaft, with permanent magnets inserted into each of the respective permanent magnet embedment slots. The permanent magnet embedment slots each have both a magnet storing portion, and a buffer and other members storing portion which extends to the magnet storing portion. Once a permanent magnet is stored inside the magnet storing portion, a buffer member, and a pushing member are used to secure the permanent magnet inside the rotor core.
