as in the initial conditions the motor is at rest,the speed 
of the motor is zero.
           
        using KVL equation,
                           V=Eb+IaRa,Eb=back EMF
                                     Ia=armature current
                                     Ra=armature resistance
(very small),V=input supply(around 220V dc)
      Initially speed=0
    implies Eb=0
      Ia=(V/Ra)   which is very high value,since V is high 
and Ra is very small.
            Hence starting resistance or 3 point starter 
are used.
