NO

Why starter?
When DC Motor is suddenly connected to a supply source,
it creates stresses on the armature and supply system.
Since at standstill the armature is not developing any back
e.m.f, so the more current than the rated current
and this will cause damage to the motor.

What the starter do ?

A Motor Starter is used for the smooth starting of a motor.
It consists mainly of a variable resistance placed in
series with the armature.
The purpose of this resistance is to restrict the armature
current to a safe value for starting and accelerating.

The other uses of using a Motor Starter is
· To disconnect the motor in case of an overload
· To disconnect the motor when the supply voltage fails
· To disconnect the motor when the field current is reduced
beyond limit. 

Answer / vignesh

guys we can start the dc motor without starter by using no of resistors in series depending on the rated current

Answer / senthilnaathan

if the starter is based on increase in resistance can we include some series resistances so as to control the current flow..??
which inturn acts as a starter here??
can this be possible??

Answer / mallikarjuna chowdary

dc mototr doesnt require starter
high starting torques
carbon brushes require to control current

Answer / guest

yes

Answer / guest

No

Answer / thavam

DC motor starting current=starting voltage
for Ex:220 volt= 220 amps
because current limiting used for starters

Answer / abhishek pandey

without starter we do not start DC Motor

Answer / nakkeeran

yes..without using the starter ..surely we can run the dc
motor.........
