する永久磁石同期機。[Scope of Claim for Utility Model Registration] A laminated rotor core is divided into equal parts along the circumferential direction, permanent magnets are clamped between each rotor core, and each rotor core is formed in the lamination direction. In a permanent magnet synchronous machine in which the rotor cores are fixed by inserting fasteners into the holes, when the rotor cores are inserted into the rotor cores, the spacing increases from the inner diameter side to the outer diameter side of the rotor cores. A hole corresponding to the cross-sectional shape of the fastener is formed in the rotor core and a retaining plate attached to both end surfaces of the rotor core in the lamination direction of the rotor core. A permanent magnet synchronous machine, characterized in that the rotor core is fixed by caulking by inserting the fastener into the hole, and inserting the fastener into the hole.
