A 25-kW, 230-V shunt motor has an armature resistance of 0.11 and a field resistance of 117.
Question:
A 25-kW, 230-V shunt motor has an armature resistance of 0.11Ω and a field resistance of 117Ω. At no load and rated voltage, the speed is 2150 r/min and the armature current is 6.35 A. At full load and rated voltage, the armature current is 115 A and, because of armature reaction, the flux is 6 percent less than its no-load value. What is the full-load speed?

I am Josabanta Jani , I completed my Masters in applied geology from NIT Rourkela. During my college time I realised that some of my friends able to teach more perfectly then some of my professors. And some homework and problems were difficult to understand and took lot of time . That time I got inspired to become a tutor , to help students who are scavenger for knowledge.
After college I started teaching in some private classes . And it’s been 2 year doing this tutor job . And I feel like nothing is more interesting then teaching and discussing with other students.
So I truly wish to benefit students . And I response quickly.
Feel free to contact me with questions.
