Characteristics of Series Wound DC Motors
- High Starting Torque: Ideal for applications requiring rapid acceleration, like cranes, hoists, and electric locomotives.
- Poor Speed Regulation: Speed decreases with increasing load due to the relationship between current and magnetic field.
- High Current Draw: The series connection can lead to high armature currents, requiring careful design considerations.
- Simple Construction: Series wound DC motor has simple design and low maintenance requirements are required.
- Cost-effective: Due to simple design, series wound DC motor is more cost-effective.
- Sparking: When brushes make contact with commutator, sparks are generated during the motor operation.
Series Wound DC Motor or DC Series Motor
In electric motors, the series wound DC motor or DC series motor is one of the types of self-excited DC motor. The field winding of the series wound DC motor is internally connected to the armature winding and stands out for its robust starting torque and unique characteristics. Whereas in the shunt wound DC motor, the field winding is connected in parallel with the armature winding.
In this article, we will cover the topics of Construction, Voltage and current equation, Speed regulation and with the advantages, disadvantages and applications of series wound DC motor or DC Series Motor.
