Question
Hi, can you help me to find out why I'm not getting the right result? (see my work attached). I should get w= 123.04 rad/s as a result. In the given exercise I need to find Current Ia, speed w and Torque Te.
This is the second part of the exercise, in the first part I had to calculate If= 1.875 A, Ra= 0.2 ohms and Rf= 40 ohms. Ke and KT are the same and their value is 0.3.
I feel I have done something wrong in the equation to don't work out, can you help? As I cannot proceed to calculate Ia and Te if I don't get the right result.
