| Abstract: | This paper briefly describes the starting process of DC motor and its requirements,introduces the simplified model of shunt DC motor and its characteristics,and proposes two common connection methods of shunt DC motor starting circuit.A detailed mathematic derivation on the parameters of armature current and excitation flux in the starting circuit was carried out.The results show that the armature current and excitation flux in the former starting circuit are larger than that in the latter,thus the electrom... |
