🔍 Key Concepts

• DC motor winding types: series, shunt, compound, permanent magnet • Relationship between torque and armature current in different DC motor designs • What is meant by inherent speed regulation (how much speed changes from no-load to full-load)

💭 Think About

• Which DC motor type is known for very high starting torque but poor speed regulation as load changes? Eliminate that choice. • Think about a motor driving equipment that must keep nearly constant speed even when the load goes up or down—what winding arrangement is normally used? • For each motor type, ask: when load increases and current rises, does the field become stronger, weaker, or stay nearly constant—and how would that affect speed?

✅ Before You Answer

• Identify which motor type has a field winding in parallel with the armature and ask how that affects field strength as load changes. • Recall which motor is typically used where constant speed is more important than high starting torque (e.g., fans, machine tools). • Before choosing, match each option to its typical characteristics: starting torque level and quality of speed regulation.
