PURPOSE:To increase generating efficiency, by winding a field winding only to plural pairs of slots diametrically facing to each other successively, continuously and concentratedly, and making remaining slots empty. CONSTITUTION:A rotor 20 has 28 slots. The 1st winding 42a is wound between 1st-4th and 15th-18th slots diametrically facing to each other, the 2nd winding 42b between 5th-7th and 19th-21st slots diametrically facing to each other, and the 3rd winding 42c between 12th-14th and 26th-28th slots diametrically facing to each other. This enables the concentration of the winding so as to avoid the formation of empty slots liable to cause the magnetic flux leakage between each of the windings, therefore, the increase of power generation efficiency can be realized. |
