TheexcitationmodeofDCmotorreferstothesupplymodeofmotorexcitationcurrent.Accordingtotherelationshipbetweentheexcitationbranchandarmaturebranch,theexcitationmodeisasfollows:
1,ShuntDCmotor
TheexcitationwindingoftheShuntDCmotorisparalleltothearmaturewinding.Asashuntgenerator,theendvoltageofthemotoritselfissuppliedtotheexcitationwinding.Asashuntmotor,theexcitationwindingssharethesamepowerwiththearmature,andinperformance,theexcitationisthesameasthatoftheexcitationDCmotor.
