Question 1 of 27070

Q

The speed of a DC series motor is determined:

🔍 Key Concepts

• Speed characteristics of a DC series motor • How load current affects both field strength and armature torque in a series motor • Difference between construction elements (poles, commutator) and what actually governs speed

💭 Think About

• Think about what happens to the speed of a DC series motor when the load is suddenly reduced or removed—does it speed up or slow down, and why? • Which part of the motor changes when load current changes, and how does that change affect speed? • Are the number of poles or the commutator typically used to CONTROL speed in practice, or are they mainly construction features?

✅ Before You Answer

• Verify how armature current and field current are related in a DC series motor • Check what parameter is directly linked to speed in the basic DC motor speed equation (back EMF, flux, and current) • Confirm whether construction details like commutator and pole pairs are normally used to vary speed under operating conditions
