| Abstract: | The wonting principle of frequency controlled circuit for fan motor of the diesel locomotive is evaluated. Harmonic analysis and calculation are conducted for the phase voltage waveform of the moter. Now that the fan torque demand is satisfied, the excitation current of the auxiliary A. C. generator should remain constant to prevent the magnetic circuit of the moter from saturating under low frequency condition. |
