內燃机车的主电路(图1)由一台牵引发电机和6台他激牵引电动机1～6组成。他激直流牵引发电机具有10个极和一个串联的起动绕组。TD—804型新发电机的主要尺寸和重量,几乎与TDB02型发电机的相同。但新型发电机在电枢槽形状、绕组截面、主极绕 The main circuit of the diesel locomotive (Figure 1) consists of a traction generator and six hesitation traction motors 1 ~ 6. He excited DC traction generator has 10 poles and a series of starting windings. The main dimensions and weight of the TD-804 new generator are almost the same as those of the TDB02 generator. But the new generator in the shape of the armature slot, winding cross section, the main pole around
