Starlight generator

There are two kinds of control switches in the electric start system of generator set: electromagnetic type and mechanical type. The electromagnetic switch is driven by the electromagnetic force to pull the fork to start. When starting the diesel engine, press the switch. At this time, the circuit is as follows: the battery switch, the connecting post 5, the iron absorption coil, the connecting post, the generator and the iron battery. The current flowing through the iron suction coil makes the core magnetized to produce suction force, and the moving contact is sucked down and closed with the static contact. At this time, the circuit flowing through the starting switch is as follows: the battery terminal 4 moves the contact point and the static contact keeps the coil; the attracting coil is connected with the pole 3 and the starting line of the starter  is equipped with an iron storage battery. At this point, the current flows through the DC motor, but because ...
