The ac motor work on the principal of mutul induction.when
ac motor connect on dc supply,then donot produce mutul
induction by dc supply.becouse not pressent frequency in dc
supply.so motor is not rotate. the impedance of motor very
low by dc supply,so motor burnout from dc supply.

armature is that part in which current is induced since in dc motor we supply current to the conductor so why we call it armature?
