Kindly please solve what is ask. I want a complete and handwritten solution so that I can understand. Thank you!!'"
An automatic starter circuit is to be designed for a shunt motor rated at 20 hp, 240 V, and 75 A. The armature resistance of the motor is 0.12 Ω, and the shunt field resistance is 40 Ω. The motor is to start with no more than 250 percent of its rated armature current, and as soon as the current falls to rated value, a starting resistor stage is to be cut out. How many stages of starting resistance are needed, and how big should each one be? Can you explain the answer with explanatory sketches or steps? Thanks in advance.
