Embodiment Construction
[0008] The present invention will be further described below
[0009] There are two sets of windings on the stator, one is the direct-axis winding that generates the output voltage, the other is the horizontal-axis winding that generates the AC voltage, a fixed capacitor is connected in series on the horizontal-axis winding, and there is a magnetically conductive rotor body on the rotor. Ventilation holes are evenly opened on the rotor body, and NdFeB permanent magnets are glued on the outer circle of the body, and the magnetic steel must be fixed reliably. There is a pair of additional poles (or voltage stabilizing poles) composed of magnetizers placed on the rotor. The function of the additional poles is to maximize the magnetic flux under load. The material of the magnetizers should consider the magnetic permeability and strength. Requirements, and the shape is determined by the analysis of the magnetic field distribution. There should be enough clearance between the addit...
