SHUNT MOTOR A shunt motor is connected in the same way as a shunt generator. The field windings are connected in parallel (shunt) with the armature windings. The circuit for a shunt motor is shown in figure 2-4. Figure 2-4. – Shunt-wound dc motor. Once you adjust the speed of a dc shunt motor, the […]

COUNTER EMF
COUNTER EMF While a dc motor is running, it acts somewhat like a dc generator. There is a magnetic field from the field poles, and a loop of wire is turning and cutting this magnetic field. For the moment, disregard the fact that there is current flowing through the loop of wire from the battery. […]
