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 :)
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.
By the use of auto transformer and bridge rectifier we can start dc motor.
yes
Startor is a safety device which is protect the motor from short circuit and over load. Two point startor use for Dc series motor. Ans- majit khan (Asmacs itc) my favorite teacher "kanhu charan pradhan"
starter is used in dc motor to reduce the initial starting torque...so that the dc machine could be protected from damage.... ..and to avoid max ..current flowing ..from it it can damage whole ..moter structure

A two-point starter is used to control the starting of electrical machines, such as DC motors. It helps limit the initial current surge during the starting process by gradually increasing the voltage applied to the motor through the use of resistance. This protects the motor's windings and prevents damage due to high inrush current.
yes

to control on of operations
In DC series motor, field and armature are in series. so we use only two points. They are line and armature. therefore we use two point starter.
By the use of auto transformer and bridge rectifier we can start dc motor.
Examples of DC electric motors are the starter in your car and the motor in a DC controlled elevator, to name just two.
