Question 337Electricity & Electronics - QMED

The correct answer is C) compound-wound DC motor. The illustration EL-0054 depicts the electrical diagram of a compound-wound DC motor. This type of motor has both a series field winding and a shunt field winding, which is the defining characteristic of a compound-wound DC motor. The series field winding provides additional torque at low speeds, while the shunt field winding maintains a constant magnetic field across a range of speeds. The other options are incorrect because a shunt-wound DC motor has only a shunt field winding, a permanent magnet DC motor has a permanent magnet instead of a field winding, and a series-wound DC motor has only a series field winding.
