Diagram for question 29
AI Explanation
The correct answer is C) series wound. The wiring diagram in figure "C" of illustration EL-0054 represents a series wound DC motor. In a series wound motor, the field winding is connected in series with the armature winding, forming a single circuit. This configuration allows the motor to develop high starting torque, which is a desirable characteristic for many applications. The other answer choices are incorrect because: A) a shunt wound motor has the field winding connected in parallel with the armature, B) a compound wound motor with long shunt has the field winding connected in parallel and series with the armature, and D) a compound wound motor with short shunt has the field winding connected in series and parallel with the armature.
