04 A 240-V, 100-A DC shunt motor has compensating windings and interpoles. Its parameters are: RA = 0.14 2, Np = 1500 turns, Rp = 2002, nm = 1200 rpm Radj = 0 to 300 2, currently set to 120 2. The magnetization curve at 1200 r/min is shown in Fig. 24. 300 Speed 1200 in 250 200 Interalmented voltage Ex V 150 100 50 0 0.0 0.25 0.50 1.25 1.50 0.75 1.00 Field current. A Fig. 24 (a) What is the no-load speed (when la = 0) of this motor when Radi = 120 s2? (5 Marks) (b) What is its full-load speed? (5 Marks) c) Under no-load conditions, what range of possible speeds can be 5 Marks) achieved by adjusting Radi? (d) Describe the methods to control the speed of DC Shunt Motors. Which method is used to achieve the speed above base speed and which method is used to achieve speed below base speed? (10 Marks)
