🔍 Key Concepts

• Series DC motor relationship between load and speed • How armature current and torque change when mechanical load is reduced • Why series motors are dangerous to run with no load

💭 Think About

• Think about what happens to the current drawn by a series motor when the load is suddenly reduced. Does it go up or down? • If the current changes, what happens to the strength of the field and therefore to the motor’s speed? • Why are series DC motors usually required to always have a mechanical load connected?

✅ Before You Answer

• Recall that in a series DC motor, the field winding and armature are in series, so the same current flows through both. • Consider whether reduced load leads to more or less back EMF, and how that affects speed. • Verify which option describes a potentially dangerous overspeed condition for a series DC motor when the load is taken off.
