摘要： PROBLEM TO BE SOLVED: To provide a rotary machine which enables variable-speed operation over a wide range from low speed to high speed with high output, and achieves efficiency improvement, reliability improvement and manufacturability improvement over a wide operation range.SOLUTION: A variable magnetic force magnet 5 is inserted into a magnet inserting hole provided in the center of a magnetic pole 1, and a fixed magnetic force magnet 4 is inserted into magnet inserting holes 3A, 3B disposed asymmetrically with respect to a geometrical center 5A of the variable magnetic force magnet 5. Thus, a magnetic center 1a of the magnetic pole 1 and the geometrical center 5a of the variable magnetic force magnet 5 are configured to be deviated in a circumferential direction. Further, by arranging a plurality of magnetic poles having different deviation amounts side by side in the circumferential direction or in an axial direction, harmonic waves of a voltage induced in stator winding are reduced while mitigating demagnetization of a permanent magnet, the variable magnetic force magnet 5 is irreversibly magnetized by a magnetic field created from a current of armature winding to change a total interlinked magnetic flux amount, thereby enabling variable-speed operation over a wide range with high output. At the same time, high efficiency can be obtained over a wide operation range.

摘要： PROBLEM TO BE SOLVED: To uniformly magnetize the upper and lower layers and intermediate layer of a variable magnetic-force magnet.
SOLUTION: A rotor 1 is composed of a rotor core 2, the variable magnetic-force magnets 3 and fixed magnetic-force magnets 4. The variable magnetic-force magnets 3 are configured by superposing magnet variable magnetic-force magnets 3a and 3c having a strong coercive force and the variable magnetic-force magnets 3b having a weak coercive force in the direction of magnetization of each magnet. The magnets superposed in series are arranged in the rotor core 2 at positions where the direction of magnetization is the d-axis direction. The fixed magnetic-force magnets 4 and 4 are arranged at positions where the direction of magnetization is the d-axis direction on both sides of the magnets superposing the variable magnetic-force magnets 3 and the fixed magnetic-force magnets 4a in series. When the interlinking magnetic flux of the variable magnetic-force magnets 3 is reduced, a magnetic field in the direction opposite to the direction of magnetization of the variable magnetic-force magnets 3 is worked by a current in an armature winding. Since the intermediate layer receiving a comparatively weak magnetic field in the variable magnetic-force magnets 3 is composed of the variable magnetic-force magnets 3b having the weak coercive force, the whole of the variable magnetic-force magnets 3 is magnetized uniformly.

摘要： PROBLEM TO BE SOLVED: To provide a totally closed type small size rotary electric machine which assures high output power. SOLUTION: A rotor shaft 11 is formed as a hollow shaft including a gap 13. Accordingly, the cooling performance of rotor can be improved and reliability can also be improved by reducing weight of the rotor and supplying a coolant 17 into the rotor shaft 11. Moreover, since the center portion 14 of the rotor hollow shaft 11 is formed as a solid body, rigidity of the rotor shaft can be increased and higher rotating velocity can also be realized. Moreover, a cooling path 16 in the radial direction is provided to the rotor shaft 11, rotor iron core 4 and stator iron core 1. Consequently, the coolant 17 can be supplied through the centrifugal effect of rotation in order to cool not only the rotor shaft but also the rotor iron core, stator iron core, armature coil and the entire part of the rotary electric machine. As a result, the cooling performance can be improved remarkably.
