🔍 Key Concepts

• DC motor basics: relationship between armature, field, and torque production • Commutator and brushes: how they interact to produce unidirectional torque from DC supply • Difference between armature winding current and field winding current

💭 Think About

• In a DC motor, what has to stay effectively in the same direction relative to the main field so that torque doesn’t reverse every half turn? • Which part of the motor actually connects to the rotating armature: the field poles or the armature windings? • If the current wasn’t periodically switched as the armature rotated, what would happen to the direction of torque?

✅ Before You Answer

• Identify which winding is on the rotor (armature) and which is on the stator (field poles) • Ask: does the commutator act on the magnetic circuit (reluctance, flux path) or the electrical connections (current direction to the armature)? • Eliminate any options that describe adjustments done by brush position, not by the commutator’s fundamental function
