Web11. Using the shunt generator drawing from DC generator worksheet #2, assume it is rated for 125 volts, 25 kilowatts; armature resistance is 0.08 ohms; shunt field circuit resistance is 25 ohms. Calculate: a ) The induced emf in the armature at rated load.. b) The watts lost in the armature. C) The watts lost in the shunt field circuit. Webure 2. We have the same shunt field as used in Figure 1, GF1-GF2. We also have another field, wound with heavy wire, on the same pole pieces as GF1 and GF2. This wire was usu-ally wound directly on the iron poles, with GF1-GF2 wound over it. The terminals of the damping field were connected, causing the field to short-circuit itself. The ...

WebConsider the field magnetization characteristics of a d.c. shunt generator shown in the Fig. 1. The Fig. 1 shows that generator voltage builds in step till point A. This point is intersection of field resistance line with the open circuit characteristics (O.C.C.). The voltage corresponding to point A is the maximum voltage it can generate. WebA 230V, 1800rpm, long-shunt, cumulative compound motor has a shunt field resistance of 460 \Omega, series field resistance of 0.2 \Omega, and armature-circuit resistance of 1.3 \Omega.
