When discussing motors, what is a unique feature of series motors regarding their field windings?

  1. Consist of many turns of thin wire

  2. Connected in parallel with the armature

  3. Consist of relatively few turns of heavy wire

  4. Do not have field windings

The correct answer is: Consist of relatively few turns of heavy wire

Unlike traditional motors with multiple field windings, series motors have the unique feature of having relatively few turns of heavy wire in their field windings. This allows for higher starting torque and current levels, making series motors ideal for applications such as electric trains. Options A and B are incorrect because these describe characteristics of other types of motors, while option D is incorrect because all motors have field windings to generate the magnetic field necessary for rotation.
