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： 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.
摘要翻译：在退磁和磁化期间可以防止磁化电流的增加，并且可以在从低速到高速的宽范围内的高功率输出下实现可变速度操作。转子（1）由转子铁芯（2），可变磁力磁铁（3）和固定磁力磁铁（4）构成。可变磁力磁体（3）和固定磁力磁铁（4a）在其磁化方向上重叠以形成一系列磁体。一系列磁体位于转子芯内的磁化方向为d轴方向的位置。在可变磁力磁铁（3）和固定磁力磁铁（4a）的一系列磁铁的两侧，固定磁力磁铁（4b，4b）位于磁化方向为 d轴。当可变磁力磁铁的磁链减小时，电枢线圈的电流允许磁场沿与可变磁力磁铁的磁化方向相反的方向作用。当可变磁力磁铁的磁通增加时，电枢线圈的电流允许磁场沿与可变磁力磁铁的磁化方向相同的方向起作用。

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.
