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 four point DC motor starter uses four points to operate, thereby its name. The four point system is used to give the armature more protection from a high current start up.
to operate the motor in a desired and a safe way!
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

Ans- majit khan -we know starter is a safety device. Two point starter is used for Dc series motor. In two point starter all the thing's are connected in series.
By the use of auto transformer and bridge rectifier we can start dc motor.
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.
