Three Point Dc Motor Starter Diagram. All have a face plate rotator switch with a connected group of current limiting resistors. A 3 point starter is a device that helps in the starting and running of a dc shunt motor or compound wound dc motor similar to a 4 point starter.
A 3 point starter is a device that helps in the starting and running of a dc shunt motor or compound wound dc motor similar to a 4 point starter. The arm is spring loaded and is rotated in the clockwise direction gradually reducing the armature resistance as the motor accelerates. Mainly there are three main points or terminals in 3 point.
L shall be connected to either positive or negative terminal of dc supply.
The three types of starters include a switch namely face plate rotator through an associated set of current limiting transistors. There are different types of manual starters available for dc motor namely 2 point starter 3 point starter and 4 point starter. Various types of manual starters for dc motors commonly known as two point three point and four point starters are available. A degree of similarity exists among these starters.
