Question#2 A linear machine has the following characteristics: B = 0.5 T into page I = 0.5 m R= 0.25 Q Vg = 120V a. If this bar has a load of 20 N attached to it opposite to the direction of motion, what is the steady-state speed of the bar? b. If the bar runs off into a region where the flux density falls to 0.45 T, what happens to the bar? What is its final steady-state speed? c. Suppose VB is now decreased to 100 V with everything else remaining as in part (b). What is the new steady-state speed of the bar? d. From the results for parts (b) and (c), what are two methods of controlling the speed of a linear machine (or a real de motor)?
