Three point starter and four point starter~

Answer 1

The most significant difference between the three point and the four-point starter is that in three-point starter the no voltage coil (NVC) is connected in series with the field winding whereas in four-point starter the NVC is directly connected to the supply voltage.

Here's your Answer →

• The most significant difference between the three point and the four-point starter is that in three-point starter the no voltage coil (NVC) is connected in series with the field winding whereas in four-point starter the NVC is directly connected to the supply voltage.
• In the three-point starter, the NVC is placed in series with the field winding, and thus current is equally distributed among the NVC and the field winding.
• In the four-point starter, the NVC is placed in parallel with the field winding.
• The starter which consists three terminals is known as the three-point starter. The four-point starter consists four terminals and hence called the four-point starter
