How is a DC series motor defined______________?
Show answer Hide answer
Answer: A. has its field winding consisting of thick wire and less turns
Explanation
A direct current series motor connects its field winding directly in series with armature. The field winding requires fewer turns of thick wire to handle massive currents. Thick wire minimizes internal resistance losses while carrying the total load current. Direct current motor classifications depend entirely on how field and armature are connected. Series wound configurations experience magnetic flux variations directly proportional to load current. Fewer turns ensure that the total voltage drop across the field remains small.
Traction systems and heavy cranes utilize series motors for high starting torque. Electrical engineers select specific winding geometries based on required torque and speed profiles. Understanding winding construction helps technicians diagnose internal electrical faults in motors. Poor torque is an operational characteristic rather than a definition of winding design. Starting easily without load is factually incorrect because series motors require connected loads. Having almost constant speed describes a shunt motor rather than a series motor.
