Characteristics of Series Wound DC Motors

What is a Series Wound DC Motor or DC series Motor?

It is one of the types of self-excited DC motors. In this motor, field winding is wired series with the armature winding which means the same current flows through both field and armature windings, creating a strong magnetic field proportional to the armature current. Mainly, it has two parts i.e., stator and rotor which meet electrically and magnetically. This configuration is what gives the series wound motor its defining characteristic – high starting torque....

Speed and Torque of a Series Wound DC Motor

The Series wound DC motor has a relationship between current and amount of torque is produced. The torque is directly proportional to current over a range of graph. As the armature current increases, the magnetic field strengthens, leading to a greater force between the field and the armature conductors, resulting in higher torque. The stronger magnetic field interacts with the current-carrying conductors in the armature, generating a more significant force between them. Series wound DC motor becomes extremely essential as starter motors for most industrial applications dealing in heavy mechanical load like huge cranes or large metal chunks etc. Series wound DC motors are operated for a very small time about only a few seconds, just for the purpose of starting. By understanding this relationship between speed and torque is vital for selecting the right type of DC motor for your specific application....
