Japanese Patent JP7427509
Kind Code:
B2
Abstract:
To improve distortion of an output waveform of a single phase two-wire output part of an AC generator.SOLUTION: A three-phase winding connected in a Y-connection in a phase difference of 120° as a center of a neutral point, and a single phase winding connected to the neutral point at a phase difference of 180° against a winding of one phase (a V phase) of them are provided, an induction voltage of the single phase winding is set to 1/2 of the induction voltage of a V-phase winding. The single phase winding is formed by combining a first single phase set coil 30a of an insertion pitch P2a (eight pitches) narrower than an insertion pitch P1 (ten pitches) of the three-phase winding, and a second single phase set coil 30b of an insertion pitch P2b (six pitches) further narrower than that of the insertion pitch P2a of the first single phase set coil 30a. Then, distortion of an output waveform of a voltage of the single phase two-wire output part provided between output terminals provided to an U-phase winding and a single phase winding and output terminals provided to a W-phase winding and the single phase winding is reduced.SELECTED DRAWING: Figure 3
