🔍 Key Concepts

• DC motor principle: relationship between field windings and armature current direction • Effect of reversing field polarity vs reversing armature (input) polarity • What happens if you reverse both field and input at the same time

💭 Think About

• Think about how torque is created in a DC motor: what two magnetic fields are interacting? • If you reverse the direction of current in the field winding only, what happens to the direction of rotation? What if you reverse current in the armature only? • Consider what would happen if you reversed both the field and the input at the same time—would the direction of rotation change or stay the same?

✅ Before You Answer

• Be clear on which "input leads" are meant (armature supply leads) and how they affect current direction in the armature • Recall that the direction of rotation depends on the relative directions of field flux and armature current, not just one by itself • Verify which actions actually change that relative direction, and which leave it unchanged
