Question 129Electricity & Electronics - QMED
70% to passIn a short-shunt cumulatively compound-wound DC motor, how is the shunt field connected?
Ain series with the armature
Bin series with the armature and series field
Cin parallel with the armature
Din parallel with the armature and series field
AI Explanation
The correct answer is C) in parallel with the armature. In a short-shunt cumulatively compound-wound DC motor, the shunt field winding is connected in parallel with the armature. This allows the shunt field to maintain a constant magnetic flux, regardless of changes in armature current. The series field is connected in series with the armature, providing additional torque as the armature current increases. The other options are incorrect because: A) the shunt field is not connected in series with the armature, B) the shunt field is not connected in series with both the armature and series field, and D) the shunt field is not connected in parallel with both the armature and series field.
