Answer to Question #264399 in Engineering for naz

Question

A 150V, DC shunt motor drives a constant-torque load at a speed of 1500rpm. The

armature and field resistances are 2Ω and 150Ω, respectively. The motor draws a line

current of 10A. Assume that a resistance is added in the field circuit to reduce the field

current by 25%. Calculate the armature current, motor speed, value of the added

resistance and extra field losses.
