Question 532Electricity/Electronics - QMED70% to pass
As shown in the illustrated DC machine which is configured as a generator, what type of machine is illustrated in terms of the configuration of the windings? Illustration EL-0052
AI Explanation
The correct answer is D) shunt wound.
The illustration EL-0052 shows a DC machine configured as a generator, which has the field windings connected in parallel (shunt) with the armature windings. This configuration is characteristic of a shunt wound DC machine, where the field windings are supplied with a separate current path from the armature.
The other options are incorrect because: A) a series wound machine has the field windings connected in series with the armature, B) a cumulatively compound wound machine has both series and shunt field windings, and C) a differentially compound wound machine has series and shunt field windings connected to oppose each other.
