Claims

[Scope of utility model registration request]

Winding spaces for load compensation windings of the same width are provided at opposite positions, and in the A-B half circumference divided into two by this, salient poles of the same number of lights are arranged symmetrically at equal intervals. In addition to forming the rotor core, a load compensation winding through which an excitation current proportional to the load current flows is wound in the winding space so that the A half circumference side is the N pole and the B half circumference side is the S pole,
In addition, each of the above salient poles has an N pole on the half circumference side and an S pole on the half circumference side of B.
To rotate by alternately winding excitation windings with a large number of turns and excitation windings with a small number of turns so that the excitation strength of each salient pole becomes stronger and weaker alternately, and an excitation current flows through the excitation winding. A generator characterized in that two types of different homogeneous output voltages can be obtained from a high-frequency three-phase armature winding and a low-frequency single-phase armature winding wound around a stator core.
