    摘要： According to one embodiment, a rotor is configured by a rotor core and magnetic poles. Two or more types of permanent magnets are used such that each product of coercivity and thickness in the magnetization direction becomes different. A stator is located outside the rotor with air gap therebetween and configured by an armature core winding. At least one permanent magnet is magnetized by a magnetic field by a current of the armature winding to change a magnetic flux content thereof irreversibly. A short circuited coil is provided to surround a magnetic path portion of the other permanent magnet excluding the magnet changed irreversibly and a portion adjacent to the other permanent magnet where the magnetic flux leaks. A short-circuit current is generated in the short circuited coil by the magnetic flux generated by conducting a magnetization current to the winding. A magnetic field is generated by the short-circuit current.

    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.

    摘要： According to one embodiment, a rotor 1 has rotor cores 2a, 2b divided in the axial direction. a permanent magnet 30 is mounted at the position of each of the magnetic poles of cores. The permanent magnet 30 of each magnetic pole is configured by a single tabular member that penetrates the two divided cores in the axial direction. Convex parts 31a, 31b 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 31a, 31b 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.
