Q

What type of DC motor has extremely high starting torque, but has poor inherent speed regulation?

🔍 Key Concepts

• DC motor winding types: shunt, series, compound, and permanent magnet • Relationship between torque and armature current in different DC motors • Meaning of speed regulation (how much speed changes from no-load to full-load)

💭 Think About

• Which DC motor type lets very high current flow at startup, creating very high starting torque? • Which motor type tends to have large speed changes when load changes (poor speed regulation)? • Think about which motor is commonly used where starting under heavy load is required, like cranes or winches.

✅ Before You Answer

• Review which DC motor type is known for nearly constant speed regardless of load – eliminate that choice. • Identify which motor type has speed that varies greatly with load, especially at light load conditions. • Match the motor with high starting torque AND poor speed regulation, not just one of those characteristics.
