First disconnect the automatic voltage regulator (AVR) to connect the F+ and F- terminals of the excitation winding, and use 220V. Connect two wires from the battery (provided it is is a 2200 V DC power supply (the + pole and the - pole must be distinguished), and connect the + and - poles of these two wires respectively to the + and - poles of the winding terminal excitement, start the unit and operate it at speednominal for a period. of time. This is called the “arousal test.”
The above is just one method of magnetization, but your generator is. The sudden failure of electricity generation should not be due to loss of magnetism. For example, the rectifier diode or rotary rectifier varistor is damaged, the AVR is damaged, the terminals are in poor contact, etc. If the voltage is not enough to reach 380V, you can try using the AVR to adjust it. If the adjustment is still not sufficient, it may be due to a three-phase short circuit or one or two diodes.
