🔍 Key Concepts

• In a series wound DC generator, the field winding is in series with the armature and carries full load current. • In a shunt wound DC generator, the field winding is connected across (in parallel with) the armature and line, usually with a field rheostat in that circuit. • In compound wound machines (cumulative or differential), you will see both shunt and series field windings on each pole.

💭 Think About

• Look closely at how the field winding is connected to the lead terminals (+ and -). Is it clearly in series with the armature circuit, or does it appear to be in parallel across the line? • Do you see evidence of two separate field windings per pole (one fine shunt winding and one heavier series winding), or only one type of field winding? • Given the presence and location of the field rheostat, which type of field connection does that usually control in a DC generator?

✅ Before You Answer

• Verify whether there is only one field winding on each main pole, or two distinct windings (series + shunt). • Check if the field circuit with the field rheostat appears to be connected across the line terminals, which would indicate a particular winding type. • Confirm whether any field winding is clearly shown in series with the armature conductors, which would be necessary for a series or compound machine.
