Embodiment
As shown in Figure 2, it is the stator winding schematic diagram of the high power density generator that provides of the utility model, it is to change on the basis of conventional generator shown in Figure 1, the circumferential slot number of the stator of generator is doubled, namely, at each groove An, groove Bn, increase a groove Xn after the groove Cn respectively, groove Yn, groove Zn, n=1 wherein, 2 ... i, make the stator edge of the generator that the utility model provides be circumferentially with A1, X1, B1, Y1, C1, Z1, A2, X2, B2, Y2, C2, Z2, Ai, Xi, Bi, Yi, Ci, Zi totally 6 * i groove (i is natural number, i=16 in the present embodiment), wherein, groove A1, A2 ... wind the line successively among the Ai and still constitute the first winding RZ1, groove B1, B2 ... wind the line successively among the Bi and still constitute the second winding RZ2, groove C1, C2 ... wind the line successively among the Ci and still constitute tertiary winding RZ3, the described first winding RZ1, the second winding RZ2 and tertiary winding RZ3 constitute first threephase stator winding; In addition, groove X1, X2 ... the 4th winding RZ4 of coiling formation successively among the Xi, groove Y1, Y2 ... the 5th winding RZ5 of coiling formation successively among the Yi, groove Z1, Z2 ... the 6th winding RZ6 of coiling formation successively among the Zi, described the 4th winding RZ4, the 5th winding RZ5 and the 6th winding RZ6 constitute second threephase stator winding.
Again as shown in Figure 2, described first threephase stator winding is in parallel with described second threephase stator winding, forms the high power density generator that the utility model provides, and it is essentially six-phase generator.
U=BVL(U=leads into the end electromotive force by the electrolytics formula; The B=magnetic field intensity; The speed of V=lead cutting magnetic line, the length of lead in the L=magnetic field) as can be known, the high power density generator that uses the utility model to provide, if the size constancy of generator, under the condition of same B, V, the length L of lead is equivalent to increase by one times in the magnetic field, and its power output also is doubled certainly.And under actual conditions, under the situation that increases the groove number, can the part weakening effect be arranged to magnetic field intensity, but actual bring to power can reach more than 70% also.
More than explanation is just illustrative for the utility model; and nonrestrictive, those of ordinary skills understand, under the situation that does not break away from the spirit and scope that claim limits; can make many modifications, variation or equivalence, but all will fall within the protection range of the present utility model.
