Because it has three terminals L , F and A
L - Line (connected to Supply)
F - Field (connected to field of dc motor)
A - Armature (connected to armature of DC motor)
that's y it is called 3 point starter :)
What else can I help you with?
What is the use of 3 point starter?

Difference between 3 point starter and 4 point starter?
1." the shunt connection in four point stater is provided separately form the line where as in three point stater it is connected with line which is the drawback in three point starter 2.In three point starter NVR (no voltage relay)is series with shunt if voltage falls certain value NVR De energized due to insufficient magnetic field and motor turned off. But in four point starter NVR energized directly from DC supply thus the draw back of 3 point starter rectified
Explain working and principal of 3 point starter?
When starter handle moved to first stud a reduced voltage is applied
What is a three point starter?
A three point starter is a device that is meant to help start a DC motor. A three point starter will start device without much starting current.
Draw internal connection diagram of 3 point face plate starter?
We cannot display diagrams
What is three point dc shunt motor starter?

What is the use of 4 point starter in motors?
in 4 point starter we use a protactive rasistance to control the speed of motar in 3point starter speed is uncontolled
What is the use of 4-point starter in motors?
The four-point starter eliminates the drawback of the three-point starter. In addition to the same three points that were in use with the three-point starter, the other side of the line, L1, is the fourth point brought to the starter when the arm is moved from the "Off" position. The coil of the holding magnet is connected across the line. The holding magnet and starting resistors function identical as in the three-point starter. * The possibility of accidentally opening the field circuit is quite remote. The four-point starter provides the no-voltage protection to the motor. If the power fails, the motor is disconnected from the line.
What is the difference between a 3-point starter and a four point stater?

What is the guy called that shoots the gun at races?
HE IS CALLED THE STARTER , WITH HIS STARTER (BLANK) PISTOL
How do you replace a starter on a 1995 Plymouth Voyager with 3 point 3 liter engine?
disconnect the battery disconnect the two wires at the starter with 15mm socket, a couple of extensions and a ratchet drive , take out 3 bolts and the starter comes out pull it to the right hand side of the vehicle a simple job you do not even have to raise the car off the ground
