1.The stator copper loss is all the loss caused by the stator current flowing through the stator winding.
2.Iron loss is the loss of the generator magnetic flux in the core, mainly the hysteresis loss and eddy current loss caused by the main magnetic flux in the stator core, and also includes additional loss.
3.Excitation loss is the loss generated by the rotor circuit, which is mainly the copper loss generated by the excitation current in the excitation circuit.

4. The additional electrical loss is more complex, mainly the loss caused by the end leakage flux in the nearby iron components, the loss caused by various harmonic flux, and the iron loss caused by tooth harmonics and higher harmonics in the rotor surface.
5. Mechanical loss mainly includes ventilation loss, bearing friction loss, etc.
In the daily operation of diesel generators, loss is inevitable, but through regular maintenance can effectively reduce the wear rate. The above is about the loss classification of diesel generator sets.If you want to learn more about the maintenance of generators, you can check in our user manual or directly consult us.
