PROBLEM TO BE SOLVED: To provide a permanent magnet rotor capable of facilitating maintenance of removal/attachment of a permanent magnet, withstanding the centrifugal force of high-speed rotation, and reducing leakage flux between magnetic poles. SOLUTION: This permanent magnet rotor includes rotor cores and magnetic pole cores, which are formed by overlaying a plurality of steel plates, and V-shaped permanent magnets, each of which is disposed between the rotor core and the magnetic pole at regular intervals; the rotor core and the magnetic core can be divided; a connecting means is provided which holds the permanent magnet between both cores and connects both cores; and a gap is formed between the rotor core and the magnetic pole core on the side of the outer periphery of the permanent magnet, so that disassembling reassembling of the permanent magnet when the replacement of the magnet is needed is made possible, and obtain rigidity, capable of enduring the centrifugal force of high-speed rotation, using a connecting means for firmly connecting the rotor core and the magnetic pole core.
