  • 4 Types of DC Motors and Their Characteristics

    Series DC motor. In a series DC motor the field is connected in series with the armature.The field is wound with a few turns of large wire because it must carry the full armature current. A characteristic of series motors is the motor develops a large amount of starting torque. However, speed varies widely between no load and full load.
