Accordingly, from encourage process build must have 3 requirements: 1) advocate there must be remanence in magnetic pole core; Wiring of loop of 2) magnetic field must correct, that is to say polarity is correct; Resistor of loop of 3) magnetic field is less than critical resistor (namely line of resistance of magnetic field loop must with carry characteristic curve to have nodical) for nothing.
　　
1, the dynamo does not have result swing phenomenon and reason:
　　
The output voltage of 1) exciter does not stabilize those who cause a dynamo to not have result swing: Because the output voltage of exciter cannot be stabilized, cause dynamo rotor voltage and voltaic wave motion, cause a dynamo thereby without result swing substantially.
　　
2) system does not have the allocation of result between the dynamo when voltage changes: When systematic voltage produces little change, of the dynamo without result also can produce bigger change, this is mix by the voltage of the dynamo decide without the relation of result. The adjustment that the dynamo has as follows is characteristic, by the adjustment of the dynamo characteristic and knowable: When the excitation electric current of the dynamo is constant, the exit voltage of the dynamo namely the change that the change of systematic voltage can cause a dynamo not to have result electric current, reduce without result electric current when voltage is elevatory, will increase without result electric current when voltage drop is small. Stand side by side when much stage dynamo move and when excitation electric current is constant, of systematic voltage or the dynamo that cause without result change differ characteristic decision by the attune of the dynamo without result change quantity, when the system does not have result wave motion, the generator with the small coefficient that move difference is assumed more without result allocate.
　　
2, the reason that exciter outputs voltage to fluctuate:
　　
1) exciter and 2 loop blemish cause the wave motion that outputs voltage: Exciter excitation winding and armature circle the not stable short circuit between reachs open a way, and 2 loop, yuan empty of parts of an apparatus is received wait for fluky element, what cause exciter likely to output voltage is not stable, can originally machine examination, closely 2 times through stopping loop, experiment, the output voltage that eliminates exciter and 2 loop blemish to may be caused is fluctuant.
