DC motor has following specifications including the magnetization curve and the shunt operated equivalent. (

P_(reded )=15hp
V_(T)=240V
n_(red )=1200(r)/(m)in
R_(A)=0.40\Omega
R_(s)=0.04\Omega
I_(L stand )=55A
N_(r)=2700 turms per pole
N_(su)=27 turns per pole
R_(F)=100\Omega |)
=100 to 400\Omega (a) For any non-regular operational scenario what is the maximum possible armature current
I_(A)that can flow in the motor? (b) If the resistor
R_(20)is adjusted to
140\Omega what is the rotational speed of the motor at no-load conditions? (c) What is the speed of the motor at full load? (d) If now an unexpected very big load on the rotor's axis reduces the motor's speed to 400 rpm what will be the motor's current?
