WebA shunt-wound DC motor consists of a shunt field (identified by the symbols F 1 and F 2) connected in parallel with the armature. This motor is called a shunt motor because the field is in parallel to, or “shunts,” the armature. Figure 3 Shunt-type DC motor. The shunt field winding is made up of many turns of small-gauge wire and has a much ... WebSpeed Control of Separately excited Dc Motor. “In this method, shunt-field current is maintained constant from a separate source while the voltage applied to the armature is varied. Dc motors feature a speed, which is proportional to the counter emf. This is equal to the applied voltage minus the armature circuit IR drop.

Web3.15 Generator characteristics. For all d.c. shunt generators, the terminal voltage decreases as the machine is loaded for the following reasons: 1. The e.m.f. generated is reduced due to the effect of armature reaction which causes magnetic saturation at one of the pole tips and hence a reduction in the flux per pole. 2.
