The Workings of the Motor Starter (part 1)

1. At Starter Switch ON

Motor starter at the position "start on"
When the starter switch is turned ON, the battery current flows through the coil to hold mass in the other hand and pull in coil, field coil and to the masses through anker. At this time hold and pull-in coil form a magnetic force in the same direction, because the direction of the current flowing in the two coils. From this incident contact plate (plunger) will move toward closing play switch, thus shifting the starter drive clutch lever moves toward the position relating to the ring gear. To more clearly the current flow is as follows:

 Battery - terminal 50 - hold in coil - mass
 Battery - terminal 50 - pull-in coil - field coil - anker- mass

Therefore, the current flowing into the coil field at that time, relatively small then anker spin slower and allow docking with the ring gear pinion becomes soft. In this situation the contact plate switch has not closed games.
