Q.5 Mention the types of DC motors.
Answer
DC motors are systematically classified based strictly on how the stationary field windings are electrically connected relative to the rotating armature: Shunt, Series, and Compound motors.
Direct Current (DC) motors are meticulously categorized according to the specific electrical topological connection existing between the primary field winding and the primary armature winding. This connection dictates their exact operational torque-speed characteristics.
- DC Shunt Motor: The field winding is explicitly connected completely in parallel across the armature. It strictly provides a relatively constant operational speed.
- DC Series Motor: The field winding is explicitly connected completely in series with the armature. It provides extremely high starting torque, ideal for heavy traction.
- DC Compound Motor: Features both series and parallel field windings simultaneously, systematically combining characteristics for specialized industrial applications.
