摘要： PROBLEM TO BE SOLVED: To provide a method of specifying magnetization and a method of specifying coercive force of a magnet, capable of accurately specifying a magnetized state for each part inside the magnet or coercive force for each part of a coercive force distribution magnet and achieving precise quality assurance.
SOLUTION: The method of specifying magnetization of a magnet includes: a step of preparing a split magnet that is a split magnet when dividing a magnet to be specified in a magnetized state into a plurality of portions while the magnetic flux density in the inside has been specified as a reference split magnet 1A, measuring a surface magnetic flux density of the reference split magnet 1A, and measuring a space magnetic flux density of space adjacent to the reference split magnet for obtaining a first measurement result; a step of forming a magnet unit 10' by allowing the reference split magnet 1A to abut on other split magnets 1A', 1A" and measuring the surface magnetic flux density of the reference split magnet 1A and the separate split magnets 1A', 1A"; and third step of specifying a magnetized state of a magnet to be specified by allocating the first and second measurement results to a calculation means comprising a determinant.

摘要： PROBLEM TO BE SOLVED: To provide a rotor of a rotary electric machine enhanced in demagnetization resistance while suppressing cost increase. SOLUTION: The rotor 104 includes a rotor core 105 and permanent magnets 111, 112, 121, 122 embedded in the rotor core. The permanent magnet 111 includes a first surface which is mainly a plane surface toward a stator side and a second surface which is a reverse surface of the first surface wherein the second surface has a shape so that both ends in the direction orthogonal with the magnetization direction of the permanent magnet are thickened in the magnetization direction from the center part at both ends, in cross section orthogonal with the rotary shaft 106, that is a cross section shown in Fig.1. The cross section orthogonal with the rotary shaft of the permanent magnet is substantially rectangular and a recessed part is provided to the center part of the side included in the second surface of rectangular four sides.

摘要： PROBLEM TO BE SOLVED: To provide a rotor for magnet-embedded motors wherein it is possible to provide coercive force sufficient to resist an inverse magnetic field exerted on a permanent magnet and yet reduce the manufacturing cost thereof and a magnet-embedded motor equipped with this rotor. SOLUTION: The rotor 1 for magnet-embedded motors is formed by embedding multiple permanent magnets 21, 21, ... in a rotor core. Each permanent magnet 21 is comprised of multiple magnet areas different in coercive force according to the magnitude of an inverse magnetic field exerted on the permanent magnet 21. A magnet area 21a relatively large in coercive force is allocated to areas at both ends of each permanent magnet 21 in which a relatively large inverse magnetic field is exerted and which correspond to both ends of the rotor core in the axial direction.
