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 rotating electric machine is provided, where a generator has an increased capacity and a reduced size achieved by electromagnetically effectively utilizing that parts of a rotor core which are outside the narrowest parts of magnetic poles of the rotor core to permit large field current and suppress an increase in temperature of rotor coils. The rotating electric machine includes a stator constructed by winding armature coils around a stator core (1), and a hollow circular cylindrical rotor. The rotor has at least one pair of magnetic poles (2), non-polar portions (3) between the magnetic poles, and interpolar portions (6) arranged in the non-polar portions. In the non-polar portions (3), a plurality of rotor slots (4) are arranged at predetermined intervals. Field windings are wound in each rotor slot (4). The cross-sectional areas (S) of the rotor slots (4) other than the rotor slots (4a) nearest to the magnetic poles (2) are gradually increased in the direction from the magnetic poles (2) to the interpolar portions (6).
