摘要： A rotor has rotor cores divided in the axial direction. A permanent magnet is mounted at the position of each of the magnetic poles of cores. The permanent magnet of each magnetic pole is configured by a single tabular member that penetrates the two divided cores in the axial direction. Convex parts are respectively provided on the outer peripheries of the respective magnetic poles of the rotor cores along the axial direction of the rotor. The convex parts are provided to positions that are displaced for each of the two divided cores. The magnetic flux density increases in the convex parts, which becomes the magnetic pole center. Since the convex parts positions are displaced to each other, a skew function can be exhibited even if the permanent magnet is mounted at the same position.

摘要： A permanent magnet-reluctance type rotating machine includes an annular stator having armature windings arranged on an inner periphery of the stator, a rotor rotatably arranged inside the stator and a plurality of permanent magnets disposed in a rotor core. One permanent magnet defining each pole is divided into two magnet pieces in a direction parallel to the magnetizing direction of the permanent magnets. Owing to the division of the magnet, the mass of each permanent magnet becomes small in comparison with that of the conventional machine, so that the centrifugal force applied on the magnet holes can be reduced. Consequently, the stress generating in the rotor core is decreased to allow the rotating machine to rotate at a higher speed.

摘要： An increase of the magnetization current can be prevented during demagnetization and magnetization, and a variable speed operation can be achieved at a high power output over a wide range of from a low speed to a high speed. A rotor (1) is configured by a rotor core (2), a variable magnetic force magnet (3) and a fixed magnetic force magnet (4). A variable magnetic force magnet (3) and a fixed magnetic force magnet (4a) are overlapped in the magnetization direction thereof to form a series of magnets. The series of magnets is located within the rotor core at a position where the magnetization direction is in the direction of a d-axis. On either side of the series of magnets of the variable magnetic force magnet (3) and the fixed magnetic force magnet (4a), fixed magnetic force magnets (4b, 4b) are located at a position where the magnetization direction is in the direction of the d-axis. When the flux linkage of the variable magnetic force magnet is reduced, a current of an armature coil allows a magnetic field to act in the reverse direction to the magnetization direction of the variable magnetic force magnet. When the flux linkage of the variable magnetic force magnet is increased, a current of the armature coil allows a magnetic field to act in the same direction as the magnetization direction of the variable magnetic force magnet.

摘要： A permanent magnet electrical rotating machine wherein the slots of stator core 2A of stator 1A are rectangular enclosed slots 4A in which triangular projecting gaps 3a are formed on the inner periphery side of this stator core 2A. The stator core 2A is cooled by passing gas through the projecting gaps 3a. The magnet flux that reaches stator core 2A from permanent magnets 6 by passing through retaining ring 8 and air gap 9 is caused to pass the inner periphery sides of the projecting gaps a of the stator core 2A. By this means, oscillation of magnetic flux density in the peripheral direction is prevented, eddy currents in the retaining ring 8 which accompany this oscillation are reduced and temperature rise prevented.

摘要： An increase of the magnetization current can be restrained during demagnetization and magnetization, and a variable speed operation can be achieved at a high power output over a wide range of from a low speed to a high speed. A rotor 1 is configured by a rotor core 2, permanent magnets 3 having a small value as the product of the coercivity and the thickness in the magnetization direction thereof, and permanent magnets 4 having a large value as the product. When reducing a flux linkage of the permanent magnets 3, a magnetic field directed to the reverse direction of the magnetization direction of the permanent magnets 3 due to a current of an armature coil is caused to act on them. When increasing a flux linkage of the permanent magnets 3, a magnetic field directed to the same direction as the magnetization direction of the permanent magnets 3 due to a current of an armature coil is caused to act on them. A short circuit coil 8 is located in a magnetic path part of each permanent magnet 4 other than the permanent magnets 3. A magnetic field due to a magnetization current induces an induced current to generate a magnetic field on the periphery of the short circuit coil 8. The generated magnetic field and the magnetization current generate a magnetic field to magnetize the permanent magnets 3.
