Relay suction characteristics

Dynamic characteristics: When Armature moves to a certain level, the current in Coil decreases not only but not to increase due to the effect of Coil inductance, Armature

When the final position is reached, the speed is maximum, and the back electromotive force at both ends of the coil is also maximum. At this moment, the current drops to the lowest point. Armature


Static characteristics: refers to the relationship between the electromagnetic force and overtravel when the armature of the coil is a certain value, the armature moves from the release position to the core surface and the movement is considered to change infinitely slowly.
