ABSTRACT:
A high-power permanent-magnet generator in which a stator winding is divided into a first winding part and second winding parts to keep a number of turns less, and capacitors are installed between any different phases to store a current therein to raise a voltage and thereby yielding a high output. The first and second winding parts of independent from one another are both made in a three-phase arrangement of U-phase, V-phase and W-phase. The first and second winding parts are wound in a way staggered one another by one or two slots separating any two adjacent teeth of the successive stator teeth. Further, output lines of three phases are connected across respective capacitors to the remaining other output lines of different phases. The output lines of the first winding part and the second winding part are all installed with respective switches.
